Abstract
A color laser printer includes chargers for charging the photosensitive drums as an image carrier on which a toner image for each print color is formed. Each charger is supported by a frame member provided rotatably around a central axis of a photosensitive drum. When a closing door is moved from a closed position where an opening portion is closed to an opened position where the opening portion is opened, the frame member is moved in conjunction with the operation, from a first position where the charger charges the photosensitive drum to a second position where a part of the opening portion in the photosensitive drum is covered.
Claims16
An image forming apparatus comprising:
- an image carrier that carries a developer image formed by developing an electrostatic latent image with a developer;
- a processing device configured to act on the image carrier;
- a frame member disposed to be movable with respect to the image carrier, the frame member supporting the processing device;
- a main frame formed with an opening portion facing the image a lid member disposed to be movable between an opened position in which the opening portion is opened and a closed position in which the opening portion is closed;
- and
- a moving mechanism configured to move the frame member, in conjunction with an operation of the lid member, between a first position in which the processing device acts on the image carrier and a second position in which the frame member covers a part of the image carrier.
A process cartridge mounted on an image forming apparatus, the process cartridge comprising:
- an image carrier that carries a developer image formed by developing an electrostatic latent image with a developer;
- a processing device configured to act on the image carrier;
- a frame member that supports the processing device and disposed to be movable between a first position in which the processing device acts on the image carrier and a second position in which different from the first position;
- and
- a holding mechanism that holds the frame member at the second position in a state where the process cartridge is detached from the image forming apparatus.
