PROCESS CARTRIDGE

PURPOSE:To smoothly disassemble even when the structure of an electrophotographic process cartridge is not known and to prevent scattering of a toner by providing members or units which constitute the process cartridge with indications to show the possible postures of the members or the units when disassembled. CONSTITUTION:On a conspicuous place of a cleaning device 4, a label 11 with an arrow 11-1 indicating the direction of disassembling and a character 11-2 indicating the upside is stuck as an indication to show the posture of the cleaning device 4 during disassembling. A similar label 12 is stuck on a developing device 7. Therefore, even when a photosensitive drum 1 is disassembled from the cleaning device 4 and the photosensitive drum 1 is removed, leaking of the recovered toner 8-1 through the aperture between a squeezing sheet 3 and a cleaning blade 2 can be prevented by setting the cleaning device 4 according to the direction indicated by the label 11. Further, when a developing sleeve 6 is disassembled from the developing device 7, leaking of the toner 8-2, 8-3 is prevented by setting the developing device 7 according to the direction indicated by the label 12 and removing the developing sleeve 6.
