<P>PROBLEM TO BE SOLVED: To provide: a developing device that can suppress a spent phenomenon of a carrier for a long period to maintain excellent development for a long period regardless of a consumption of toner and the running cost of which is low; an image forming apparatus; and a process cartridge. <P>SOLUTION: Unevenness 50 is formed as a polishing means on a blade part 35a of a second developer agitating and carrying member 35 on a downstream side thereof in a developer carrying direction. The carrier is rubbed against the unevenness 50 formed on a blade part surface of the second developer agitating and carrying member 35 to polish a carrier surface, thereby removing toner sticking on the carrier upper surface. Consequently, the spent phenomenon of the carrier can be suppressed. <P>COPYRIGHT: (C)2011,JPO&INPIT |
