Image forming apparatus
An image forming apparatus includes a main casing, a drum cartridge and a developing cartridge. The drum cartridge may include a first handle positioned at a first end of a frame of the drum cartridge. The developing cartridge may include a second handle positioned at a first end of a developing casing the developing cartridge. The main casing may include a first edge surface in the axial direction and a second edge surface opposite the first edge surface in the axial direction. The second handle may extend farther from the second edge surface than the first handle extends from the second edge surface in the axial direction in a state where the drum cartridge and the developing cartridge are attached to the main casing.
1. A drum cartridge for use with a developing cartridge, the drum cartridge comprising:
a photosensitive drum rotatable about a first axis extending in an axial direction;
a frame having first and second ends spaced apart in the axial direction and rotatably supporting the photosensitive drum, and
a first handle positioned at the first end of the frame,
wherein the developing cartridge includes:
a developing roller rotatable about a second axis extending in the axial direction;
a developing casing configured to accommodate developer therein, and having first and second ends spaced apart in the axial direction and rotatably supporting the developing roller; and
a second handle positioned at the first end of the developing casing,
wherein the drum cartridge and the developing cartridge are inserted to and removed from a slot which extends from a first edge surface of an image forming apparatus in the axial direction toward a second edge surface opposite the first edge surface in the axial direction,
wherein the first end of the frame of the drum cartridge and the first end of the developing casing are proximate the first edge surface in a state where the drum cartridge and the developing cartridge are attached to the slot, and
wherein a length defined by the second handle extending from the second edge surface is different from a length defined by the first handle extending from the second edge surface in the axial direction in a state where the drum cartridge and the developing cartridge are attached to the slot.
2. The drum cartridge according to claim 1 ,
wherein the second handle extends farther from the second edge surface than the first handle extends from the second edge surface in the axial direction in a state where the drum cartridge and the developing cartridge are attached to the slot.
3. A developing cartridge for use with a drum cartridge, the developing cartridge comprising:
a developing roller rotatable about a first axis extending in an axial direction;
a developing casing configured to accommodate developer therein, and having first and second ends spaced apart in the axial direction and rotatably supporting the developing roller; and
a second handle positioned at the first end of the developing casing,
wherein the drum cartridge includes:
a photosensitive drum rotatable about a second axis extending in the axial direction;
a frame having first and second ends spaced apart in the axial direction and rotatably supporting the photosensitive drum, and
a first handle positioned at the first end of the frame,
wherein the drum cartridge and the developing cartridge are inserted to and removed from a slot which extends from a first edge surface of an image forming apparatus in the axial direction toward a second edge surface opposite the first edge surface in the axial direction,
wherein the first end of the frame of the drum cartridge and the first end of the developing casing are proximate the first edge surface in a state where the drum cartridge and the developing cartridge are attached to the slot, and
wherein a length defined by the second handle extending from the second edge surface is different from a length defined by the first handle extending from the second edge surface in the axial direction in a state where the drum cartridge and the developing cartridge are attached to the slot.
4. The developing cartridge according to claim 3 ,
wherein the first handle extends farther from the second edge surface than the second handle extends from the second edge surface in the axial direction in a state where the drum cartridge and the developing cartridge are attached to the slot.
