发明名称 IMAGE FORMING DEVICE, ELECTROPHOTOGRAPHIC IMAGE FORMING DEVICE AND PROCESS CARTRIDGE
摘要 PROBLEM TO BE SOLVED: To provide an image forming device, an electrophotographic image forming device and a process cartridge improved in terms of developer amount detecting accuracy. SOLUTION: This image forming device is provided with a developer storage part 23d in which developer is stored, a 1st developer amount detecting means consisting of a plurality of electrodes 23a and 41 arranged in the storage part 23d, a 1st electrostatic capacity detecting means 61 for detecting electrostatic capacity between the plurality of electrodes of the 1st developer amount detecting means, and a 1st developer amount conversion means 50 for converting the detected result by the detecting means 61 into developer amount, and is constituted so that the developer amount in the storage part 23d is detected by correcting the converted result by the conversion means 50 in accordance with the detected result by the detecting means 61 in specified timing.
