Problems solved by technology

Regarding paper that cools sufficiently in a low-temperature and low-humidity environment, heating is insufficient due to a 10°C drop in the controlled fusing temperature, and, for example, image quality may decrease due to poor fusing, and poorly fused paper due to unfused toner transmission may cause the interior of the device to become dirty

Embodiment 1

[0022] figure 1 is a sectional view showing the configuration of the image forming apparatus 100 according to the embodiment of the present invention. The image forming apparatus 100 includes an apparatus main body 100A. The photosensitive drum 1 is placed in the apparatus main body 100A. A charging roller 2 , a laser scanner 3 , a developing device 4 including a developing roller 4 a as a developer bearing member, a transfer roller 5 , and a cleaning device 6 including a cleaning blade 6 a are placed around the photosensitive drum 1 . image forming system 1000 (see Figure 2B ) included via the network 206 (see Figure 2A and 2B ) of multiple image forming apparatuses 100 connected to each other ( Figure 2B , shown as copiers A and B). The network 206 used herein is a local area network (LAN) inside a company or the like or an external network configured to communicate with the outside via the Internet or the like.

[0023] The surface of the photosensitive drum 1 is ...

Embodiment 2

[0053] In Embodiment 2, the main body CPU 202 of the image forming apparatus 100 reads from the storage section 202b of the other image forming apparatus 100 (see Figure 2A ) related to the past day that provides the same data as the current day’s environmental information or data close to it, and is based on the acquired day’s environmental information stored in the storage section 202b of the image forming apparatus 100 Set image forming conditions.

[0054] Specifically, when the temperature is 22° C. and the humidity is 51% as the environmental information of copier B on that day, copier B selects a day whose temperature and humidity are equal to or close to it among the past data of copier B, and stores the selected send to copier A on the day of The copier A reads the data of the environmental information on the acquired day from the storage unit of the copier A, and sets the image forming conditions based on the environmental information. The reason is that the relat...

Embodiment 3

[0056] Figure 4is a flowchart showing the control procedure in the main body CPU 202 of the main body control section 9a according to the third embodiment. Figure 4 The control shown in is basically similar to the control of Embodiment 1, but in Embodiment 3, execution can cope with the case where both the environment detection device 204 of copier A and the environment detection device 204 of copier B fail or the power supply of copier B is interrupted. Close the control of the situation.

[0057] like Figure 4 Shown, the main body CPU 202 recognizes that the user presses the copy button of the copier A ( S101 ). The main body CPU 202 determines whether the environment detection device 204 of the copier A is normal ( S2 ). When the determination in S2 is YES (environment detection device 204 is determined to be normal), main body CPU 202 calculates image forming conditions based on the environment data of copier A ( S3 ), and starts copying ( S4 ). When the determinati...

Abstract

An image forming system, including a plurality of image forming apparatus mutually connected to one another through a network, each of the plurality of image forming apparatus being configured to form an image on a recording medium, each of the plurality of image forming apparatus including: an environment detecting device configured to detect environmental information of each of the plurality of image forming apparatus; and a control unit configured to control image forming conditions based on the environmental information detected by the environment detecting device, wherein the control unit of one of the plurality of image forming apparatus sets the image forming conditions of the one of the plurality of image forming apparatus based on the environmental information of another of the plurality of image forming apparatus through the network.

Description

technical field [0001] The present invention relates to an image forming system including a plurality of image forming apparatuses, and to the image forming apparatuses. Background technique [0002] Electrophotographic copiers are used all over the world, and thus, are required to form suitable images under various environments, such as high-temperature and high-humidity environments or low-temperature and low-humidity environments. Therefore, the electrophotographic image forming apparatus includes an environment detection sensor configured to detect temperature and humidity. According to the temperature and humidity information detected by the sensor, various printing parameters are changed. Specifically, when a copier is used in a high-temperature and high-humidity environment, for example, an ambient temperature of 30°C and a humidity of 80%, in order to prevent paper curling and retransfer, control is performed to lower the transfer bias during printing and reduce the...
