PROCESS CARTRIDGE, DEVELOPING DEVICE, AND ELECTROPHOTOGRAPHIC IMAGE FORMING DEVICE

摘要

PROBLEM TO BE SOLVED: To unnecessitate operation for shaking a process cartridge for moving the remaining toner inside a toner container part and to prevent the occurrence of a void image without requiring the improvement of the ability of the driving source of a device main body in the case of toner decrease. SOLUTION: An antenna line 26 for detecting the remaining amount of developer and a developer carrying means 30 are provided inside the toner container part 1, the means 30 is operated linked with the detection of the remaining amount of the developer so as to carry the remaining toner which can not be moved by a toner feeding member 21 within the rotating radius of the member 21, so that all the toner is carried to the roller 5. A storing means 50 storing the detection history of the developer remaining amount detecting means is provided on the process cartridge B, and toner non-existence warning is surely displayed by specific information even though the process cartridge B is moved to another device main body.
