PROCESS CARTRIDGE AND IMAGE FORMING APPARATUS

A process cartridge including: a developing device to supply a developer to a photosensitive member; and a plate-shaped elastic portion that cleans a peripheral surface of the photosensitive member, wherein, multiple grooves extend in a circumferential direction and are formed to be side by side in a rotation axis direction on the peripheral surface, the developer contains a toner including a toner particle and an organosilicon polymer having a structure represented by R-SiO3/2 covering the surface of the toner particle, and when a penetration amount of the plate-shaped elastic portion with respect to the photosensitive member is set as δ (mm), and a fixing rate of the organosilicon polymer on the surface of the toner particle is set as α (%), δ≤0.02×α−0.4 is satisfied (R represents a hydrocarbon group having at least 1 and not more than 6 carbon atoms).
