<P>PROBLEM TO BE SOLVED: To suppress lowering of residual quantity detection accuracy of a developer by a simple work in a recycling process when a developer amount to be filled is changed in recycling a used cartridge. <P>SOLUTION: A process cartridge 101 includes: a support member 16 which is arranged opposite a plate antenna 14 in a developing container 12 and has a toner detection region formed between the support member 16 and the plate antenna 14 to detect an amount of toner more than a toner amount which can be detected in a region C1 between a developing sleeve 6 and the plate antenna 14, and is electrically connected to the developing sleeve 6; and a plate 22 capable of electrically connecting the developing sleeve 6 and the support member 16. In a process for recycling the process cartridge 101, the electric connection of the developing sleeve 6 and the support member 16 by the plate 22 is disconnected according to an assembling operation of the supporting member 16 to a frame body 23 to switch a detection region of the toner amount. <P>COPYRIGHT: (C)2013,JPO&INPIT |
