Abstract:
1. A remanufacturing method for a process cartridge, wherein the process cartridge includes a drum unit and a developing unit, said drum unit supporting an electrophotographic photosensitive drum, and said developing unit supporting a developing roller for developing an electrostatic latent image formed on said electrophotographic photosensitive drum and a developer accommodating portion having a developer supply opening, said method comprising: a unit separating step of separating said drum unit and said developing unit from each other; a developing roller dismounting step of dismounting said developing roller from said developing unit; a developing refilling step, following said developing roller dismounting step, of refilling a developer into said developer accommodating portion through said developer supply opening that is exposed; a developing roller mounting step of mounting said developing roller or a fresh developing roller to said developing unit; a unit coupling process of swingably coupling said drum unit and said developing unit with each other; a first-end developing-device spacing member mounting step of engaging a first-end developing-device spacing member provided movably at one end portion side of said process cartridge with said drum unit and said developing unit to space said developing roller from said electrophotographic photosensitive drum; and a second-end developing-device spacing member mounting step of engaging a second-end developing-device spacing member provided movably at the other end portion side of said process cartridge with said drum unit and said developing unit to space said developing roller from said electrophotographic photosensitive drum, wherein said first-end developing-device spacing member is provided rotatably at said developing unit and is engaged with an opening provided at said drum unit by said first-end developing-device spacing member mounting step, and wherein said second-end developing-device spacing member is provided rotatably at said drum unit and is engaged with a projection provided at said developing unit by said second-end developing-device spacing member mounting step.
