Japan, July 14 -- CANON INC has got intellectual property rights for 'IMAGE FORMING APPARATUS.' Other related details are as follows:
Application Number: JP,2022-075516
Category (FI): G03G21/00,370,G03G21/00,310
Stage: PROBLEM TO BE SOLVED: To effectively execute a developer supply step by reducing the unnecessary consumption of developer and unnecessary interruption time of image formation.SOLUTION: An image forming apparatus 100 has: a control unit 101 that can control an image forming operation, and a supply operation to supply developer to a contact part G between an image carrier 1 and a cleaning member 51; a driving unit 21 that can drive the image carrier 1 at a first rotation speed being at least one rotation speed during the image forming operation and a second rotation speed lower than the first rotation speed; and a torque detection unit 80 that detects information on load torque during the rotation of the image carrier 1. When an instruction to start the image forming operation is input, the control unit 101 starts up the driving unit 21 to rotate the image carrier 1 at the second rotation speed and acquires a result of detection performed by the torque detection unit 80 while the image carrier 1 rotates at the second rotation speed, and based on the result of detection performed by the torque detection unit 80, can determine whether to perform the supply operation before the image forming operation.SELECTED DRAWING: Figure 5 (Grant)
