[0052] The display unit 35 includes a monitor such as an LCD, and displays various screens, etc. according to the instructions of the display signal input from the control unit 31.

[0053] <2. Unit DB> Next, the unit DB131 stored in the storage unit 13 will be described. FIG. 6 is a diagram showing an example of the contents of the unit DB131. The unit DB131 stores unit identification information, status information, and attachment information for each used unit taken out from the image forming apparatus 2a (disposal apparatus). Thereby, information regarding a plurality of units removed from the image forming apparatus 2a (disposal apparatus) and stored as inventory can be easily managed in the unit DB131. The units in the present embodiment are, for example, a fixing unit 274, a photosensitive drum unit 271b, a paper feed roller included in the conveyance unit 28, a waste toner conveyance unit included in the waste toner collection unit 29, an LCD panel 23A, and the like.

[0054] The unit identification information is information for identifying a unit. The unit identification information includes the serial number (S / N) of the main body of the image forming apparatus 2a (disposal apparatus) from which the unit was taken out and the unit name of the unit.

[0055] The status information includes life information and control parameters. The life information is information regarding the life of the unit. The life information includes at least one of remaining life (%), running distance, running time, number of printed (image formed) sheets, number of read sheets, energization time, and manufacturing date. The control unit 21 of the image forming apparatus 2 estimates the remaining life of the unit based on at least one of the running distance, running time, number of printed sheets, number of read sheets, energization time, and manufacturing date of the unit. The control unit 21 functions as an estimation unit. The control unit 21 estimates the remaining life by estimating the deterioration over time of the unit based on, for example, the manufacturing date of the unit. The control unit 21 estimates the remaining life by estimating the wear deterioration of the unit based on, for example, the running distance, running time, number of printed sheets, number of read sheets, and energization time of the unit.

[0056] The running distance is the cumulative running distance from when the unit is in a new state until it is taken out of the image forming apparatus 2a (disposal apparatus). The running distance is information corresponding to, for example, the fixing unit 274, the photosensitive drum unit 271b, etc. The running time is the cumulative running time from when the unit is in a new state until it is taken out of the image forming apparatus 2a (disposal apparatus). The running time is information corresponding to, for example, the fixing unit 274, the photosensitive drum unit 271b, etc. The number of printed sheets is the cumulative number of sheets printed from when the unit is in a new state until it is taken out of the image forming apparatus 2a (disposal apparatus). The number of printed sheets is information corresponding to, for example, the fixing unit 274, the photosensitive drum unit 271b, the paper feed roller, the waste toner conveyance unit, etc. The number of scanned sheets is the cumulative number of sheets scanned from when the unit is in a new state until it is taken out of the image forming apparatus 2a (disposal apparatus). The number of scanned sheets is information corresponding to, for example, the original document conveyance roller. The energization time is the cumulative operation time from when the unit is in a new state until it is taken out of the image forming apparatus 2a (disposal apparatus). The energization time is information corresponding to, for example, the LCD panel 23A. The manufacturing date is the date on which the unit was manufactured.

[0057] The control parameter is the control parameter of the unit that was set in the image forming apparatus 2a (disposal apparatus). The control parameter is, for example, the charging output value of the photosensitive drum unit 271b. In the image forming apparatus 2, as the photosensitive member is worn away by friction with the cleaning blade of the cleaning unit 271e, the film thickness of the photosensitive member becomes thinner. Therefore, the control unit 21 sets the charging output value of the photosensitive drum unit 271b based on the film thickness of the photosensitive member. The control unit 21 detects the degree of wear of the film thickness of the photosensitive member from the resistance value of the current flowing through the photosensitive member. Even for the same number of printed sheets, the degree of wear of the film thickness of the photosensitive member is different between continuous printing and non - continuous printing. During non - continuous printing, the photosensitive member rotates more in printing preparation, post - processing, etc. than during continuous printing, so the film thickness of the photosensitive member is more easily worn away.

[0058] The attachment information is the serial number (S / N) of the image forming apparatus 2b (reproduction apparatus) to which the unit is attached.

[0059] <3. Reproduction Operation of Image Forming Apparatus> Next, the reproduction operation of the image forming apparatus 2 in the image forming system 100 will be described. FIG. 7 is a ladder chart showing the flow of the reproduction operation of the image forming apparatus 2.

[0060] In the reproduction operation of the image forming apparatus 2, the control unit 21a of the image forming apparatus 2a (disposal apparatus) whose main body is to be disposed of receives a designation of a unit to be reused from an operator via the operation unit 22a. When the unit is designated, the control unit 21a acquires the serial number of the main body of the image forming apparatus 2a from the storage unit 25a (step A1). That is, the control unit 21a acquires the serial number for identifying the image forming apparatus 2a (first image forming apparatus). The control unit 21a functions as a second acquisition unit.

[0061] Next, the control unit 21a acquires the unit name of the designated unit from the storage unit 25a. Next, the control unit 21a generates unit identification information including the serial number of the main body of the image forming apparatus 2a acquired in step A1 and the unit name of the designated unit (step A2). That is, the control unit 21a adds the serial number of the image forming apparatus 2a (first image forming apparatus) to the name of the unit to generate the identification information of the unit. The control unit 21a functions as a first generation unit.

[0062] Next, the control unit 21a acquires the state information of the designated unit from the storage unit 25a (step A3). Next, the control unit 21a transmits the unit identification information generated in step A2 and the state information of the unit acquired in step A3 to the server 1 (step A4).

[0063] The control unit 11 of server 1 receives unit identification information and unit status information from the image forming apparatus 2a via the communication network N and stores them in the unit DB 131 (step A5). That is, the control unit 11 acquires identification information of the unit mounted on the image forming apparatus 2a (first image forming apparatus) and status information (life information and control parameters) indicating the status of the unit. The control unit 11 functions as a first acquisition unit. The control unit 11 registers the unit identification information and status information of the unit in the unit DB 131 (database). The control unit 11 functions as a registration unit. Step A5 is a first acquisition step and a registration step.

[0064] After step A4, the control unit 21a of the image forming apparatus 2a determines whether or not the unit identification information and status information of all the designated units have been transmitted to the server 1 (step A6). If there is a designated unit for which the unit identification information and status information have not been transmitted to the server 1 (step A6; NO), the control unit 21a proceeds to step A2 and executes processing for the next unit.

[0065] On the other hand, if the unit identification information and status information of all the designated units have been transmitted to the server 1 (step A6; YES), the control unit 21a causes the image forming unit 27a to print the unit identification information of all the designated units on paper. The operator removes the designated unit from the main body of the image forming apparatus 2a, attaches the paper on which the unit identification information is printed to the corresponding unit, and stores it as inventory of used units.

[0066] The operator inputs, in the image forming apparatus 2b, search conditions for a used unit (replacement unit) to be attached to the image forming apparatus 2b (reproducing apparatus). The control unit 21b of the image forming apparatus 2b receives an input operation of search conditions for a replacement unit via the operation unit 22b by the operator. That is, the control unit 21b receives the search conditions of the units registered in the unit DB131 (database) in the image forming apparatus 2b (second image forming apparatus). The control unit 21b functions as a first reception unit. Next, the control unit 21b acquires the model information of the image forming apparatus 2b from the storage unit 25b, and transmits the acquired model information and the received search conditions to the server 1 (step A8).

[0067] In step A8, the control unit 21b displays the search condition screen 231 shown in FIG. 8 on the display unit 23b, and receives the input of the search conditions for the replacement unit. In the example shown in FIG. 8, the search condition screen 231 includes a search condition input field 231a, a search button 231b, and the like. The control unit 21b receives the input of the search conditions for the replacement unit in the search condition input field 231a. The search conditions for the replacement unit include, for example, the type of the unit and the remaining life. Next, when the control unit 21b receives the pressing operation of the search button 231b by the operator, it transmits the model information of the image forming apparatus 2b and the search conditions for the replacement unit received on the search condition screen 231 to the server 1.

[0068] The control unit 11 of the server 1 receives the model information of the image forming apparatus 2b and the search conditions for the replacement unit from the image forming apparatus 2b. Next, the control unit 11 searches for the units corresponding to the received model information and search conditions in the unit DB131. That is, the control unit 11 searches for the units registered in the unit DB131 (database) based on the search conditions received by the first reception unit. The control unit 11 functions as a search unit. Next, the control unit 11 transmits the information on the search results of the replacement unit to the image forming apparatus 2b (step A9). The information on the search results of the replacement unit includes the unit identification information and the life information of the units extracted by the search.

[0069] The control unit 21b of the image forming apparatus 2b receives information on the search results of the replacement unit from the server 1. Next, the control unit 21b displays on the display unit 23b a search result screen 232 (see FIG. 9) that displays the received search results of the replacement unit (step A10). That is, the control unit 21b displays the search results by the search unit on the display unit 23b of the image forming apparatus 2b (second image forming apparatus). The control unit 21b functions as a second display control unit.

[0070] In the example shown in FIG. 9, the search result screen 232 includes a search result list 232a, a reception button 232b, and the like. In the search result list 232a, the control unit 21b displays in a list the unit identification information and life information of the units extracted by the search as the search results of the replacement unit.

[0071] The operator selects a unit to be attached to the image forming apparatus 2b (reproducing apparatus) from the search result list 232a.
