摘要: PROBLEM TO BE SOLVED: To automatically pressurize a developing roller to photoreceptor drum, when process unit is set in the body housing of an image forming apparatus. SOLUTION: On inner surfaces both left and right walls cartridge, movable operating sections 43 project outwardly, over from frame-like slide support members 40, which freely turnably attached via rotary shafts 39a 39b. When cartridge 4 loaded part inverted-triangular parts be operated 61 for projecting outer 4, brought adjacent 40. pressurized inside housing, section into contact, along upper lower recessed guidance surface 55a means 55 disposed on each sides then member 40 changes its attitude pressurizes non-pressurized state, then, 22 so as drum 13.
