Abstract
An image forming apparatus includes a drum cartridge including a photosensitive drum, a developing cartridge including a developing roller, a main assembly. The main assembly includes a first opening, a second opening, a first openable member, a second openable member, a pressing member, a first pressing releasing member for releasing the developing cartridge from the pressing member in a state in which the second openable member is in a second closed position, in interrelation with movement of the first openable member from a first closed position to a first open position, and a second pressing releasing member for releasing the pressing the developing cartridge from the pressing member in interrelation of movement of the second openable member from a second closed position to a second open position.
Claims3
An image forming apparatus comprising:
- a drum cartridge including a photosensitive drum;
- a developing cartridge including a developing roller configured to supply toner to said photosensitive drum;
- and
- a main assembly configured so that said drum cartridge and said developing cartridge are independently mountable in and dismountable from said main assembly, said main assembly including,
- a first opening through which said drum cartridge passes when said drum cartridge is mounted in and dismounted from said main assembly,
- a second opening through which said developing cartridge passes when said developing cartridge is mounted in and dismounted from said main assembly,
- a first openable member configured to move between a first closed position where said first opening is closed and a first open position where said first opening is open,
- a second openable member configured to move between a second closed position where said second opening is closed and a second open position where said second opening is open,
- a pressing member configured to press said developing cartridge so that said developing roller contacts said photosensitive drum,
- a first pressing releasing member configured to release said developing cartridge from said pressing member in a state in which said second openable member is in the second closed position, in interrelation with movement of said first openable member from the first closed position to the first open position, and
- a second pressing releasing member configured to release said developing cartridge from said pressing member in interrelation of movement of said second openable member from the second closed position to the second open position.
