Embodiment Construction

[0022]

[0023] like figure 1 As shown, the image forming apparatus 100 of this embodiment includes a printing unit 106 including a paper feeding unit 101 , a paper feeding unit 102 , an image forming unit 103 , an intermediate transfer unit 104 and a fixing unit 105 . The printing unit 106 conveys the paper P along the paper conveyance path PP, and forms a toner image based on image data of an image to be printed. Then, the printing unit 106 prints (transfers) the toner image onto the paper P being transported. In addition, the image data used as the basis of the toner image is the image data obtained by reading the document by the image reading unit 107 described later, or the image data obtained from the user terminal 300 (refer to image 3 ) image data sent to the image forming apparatus 100.

[0024] The paper feed unit 101 includes a pick-up roller 11 and a paper feed roller pair 12 , and feeds paper P accommodated in a paper feed cassette 13 to a paper feed path PP....

Abstract

When an image forming apparatus detects that an amount of toner returns to a first reference amount or more without replacement of a container after determining that a toner low state has occurred, the image forming apparatus controls a container memory unit to store predetermined information. When performing toner supply, if the predetermined information is stored, the image forming apparatus performs at least one of a first process for changing a time ratio so that a rotation period ratio of a supply screw is increased and a second process for changing the first reference amount to be increased.

Description

technical field [0001] The present invention relates to an image forming apparatus including a developing device for developing an electrostatic latent image into a toner image. Background technique [0002] Conventionally, there is known an image forming apparatus that develops an electrostatic latent image into a toner image and transfers (prints) the toner image onto paper. Such an image forming apparatus includes a developing device that supplies toner to an electrostatic latent image and develops the electrostatic latent image into a toner image. [0003] The developing device contains toner inside, and the toner in the developing device is continuously consumed due to execution of printing (the amount of toner in the developing device is continuously reduced). Therefore, an image forming apparatus including a developing device is generally provided with a toner container (toner cartridge) that stores replenishing toner. And, when it is necessary to replenish toner to...
