Abstract
An image forming apparatus includes a casing, a process cartridge, a drawer configured to support the process cartridge and move between an inside position and an outside position. The drawer includes a bottom plate. The bottom plate is configured to support the process cartridge. The bottom plate has a flat surface on one side of the bottom plate and further has a recessed portion recessed relative to the flat surface toward the other side of the bottom plate. The drawer has the flat surface at a portion of the one side. The recessed portion has a support surface configured to support the process cartridge.
Claims24
An image forming apparatus comprising:
- a casing;
- a process cartridge including a photosensitive drum with an axial direction;
- and
- a drawer configured to move between
- an inside position at which the drawer is located inside the casing and
- an outside position at which the drawer is located outside the casing in a sliding direction orthogonal to the axial direction of the photosensitive drum,
- wherein a projected plane of the process cartridge projected in the axial direction of the photosensitive drum overlaps a projected plane of the drawer,
- wherein the overlapping area of the projected plane of the process cartridge and the drawer is between 3% and 30% inclusive of a total area of the projected plane of the process cartridge, and
- wherein the projected plane of the process cartridge is an area based on a projection of the process cartridge onto a virtual plane that is perpendicular to the axial direction and the projected plane of the drawer is an area based on a projection of the drawer onto the virtual plane.
An image forming apparatus comprising:
- a casing;
- at least two process cartridges, each of the process cartridges including a photosensitive drum and each photosensitive drum having an axial direction;
- and
- a drawer configured to move between
- an inside position at which the drawer is located inside the casing and
- an outside position at which the drawer is located outside the casing in a sliding direction orthogonal to the axial directions of the photosensitive drums,
- the drawer including
- a plate extending both in the axial directions and in the sliding direction and having a flat surface,
- wherein projected planes of the process cartridges projected in the axial directions of the photosensitive drums overlap a projected plane of the drawer,
- wherein the overlapping areas of the projected planes of the at least two process cartridges overlap the projected plane of the drawer between 3% and 30% inclusive of a total area of the projected planes of the at least two process cartridges, and
- wherein the projected plane of each of the process cartridges is an area based on a projection of each process cartridge onto a virtual plane that is perpendicular to the axial directions and the projected plane of the drawer is an area based on a projection of the drawer onto the virtual plane.
