Abstract
An image forming apparatus includes a main assembly and a process cartridge. The developing unit of the process cartridges includes a first portion to be urged and a second portion to be urged. The main assembly includes a guide portion for guiding the first portion to be urged and the second portion to be urged during mounting of the process cartridge in the main assembly. The guide portion includes, in a state in which the process cartridge is mounted in the main assembly, a first hole for permitting thereinto entry of the first portion to be urged and a second hole for permitting thereinto entry of the second portion to be urged.
Claims6
A process cartridge comprising:
- a photosensitive drum unit including a photosensitive drum rotatably supported therein;
- a developing unit including a rotatably supported developing roller for developing a latent image formed on said photosensitive drum, said developing unit being movably connected with said photosensitive drum unit so that said developing roller is capable of moving toward and away from said photosensitive drum;
- a first projected portion projected from said developing unit in a direction away from said developing roller at a position in one longitudinal end portion side of said developing unit and in a side opposite from said developing roller as seen along a longitudinal direction;
- and
- a second projected portion projected from said developing unit in a direction away from said developing roller at a position in the other longitudinal end portion side of said developing unit and in a side opposite from said developing roller as seen along the longitudinal direction,
- wherein said second projected portion has a length measured in the longitudinal direction that is larger than a length of said first projected portion.
A process cartridge comprising:
- a photosensitive drum unit including a photosensitive drum rotatably supported therein;
- a developing unit including a rotatably supported developing roller for developing a latent image formed on said photosensitive drum, said developing unit being movably connected with said photosensitive drum unit so that said developing roller is capable of moving toward and away from said photosensitive drum;
- a first hole portion recessed toward said developing roller at a position in one longitudinal end portion side of said developing unit and in a side opposite from said developing roller as seen along a longitudinal direction;
- and
- a second hole portion recessed toward said developing roller at a position in the other longitudinal end portion side of said developing unit and in a side opposite from said developing roller as seen along a longitudinal direction,
- wherein said second hole portion has a length measured in the longitudinal direction that is larger than a length of said first hole portion.
