摘要： Disclosed is a copper alloy containing 1.0% to 3.6% of Ni, 0.2% to 1.0% of Si, 0.05% to 3.0% of Sn, 0.05% to 3.0% of Zn, with the remainder including copper and inevitable impurities. The copper alloy has an average grain size of 25 pm or less and has a texture having an average area percentage of cube orientation of 20% to 60% and an average total area percentage of brass orientation, S orientation and copper orientation of 20% to 50%. The copper alloy has a KAM value of 0.8 to 3.0 and does not suffer from cracking even when subjected to U-bending. The copper alloy has excellent balance between strengths (particularly yield strength in a direction perpendicular to the rolling direction) and bending workability.

摘要： Image forming unit has a photosensitive drum unit and a developing unit. The photosensitive drum unit has drum shafts extending outward from opposite sides thereof. The developing unit has a through-hole and a drum shaft mounting groove for receiving the drum shafts, and developing unit rotary shafts extending outward from opposite sides thereof. An engagement lever and a toner returning cylinder are provided in the photosensitive drum unit, and a shutter is provided in the developing unit. The toner returning cylinder and the shutter are disposed between the waste toner tank of the photosensitive drum unit and the toner returning pipe of the developing unit so that they are detachable and separable from each other. Further, a mechanism is provided for pressing the developing roller onto the photosensitive drum when the photosensitive drum unit is mounted to the developing unit or when the photosensitive roller is driven.
