Abstract
A photoreceptor cartridge and an image forming apparatus having the photoreceptor cartridge. The photoreceptor cartridge includes: a first assembly configured to include a first frame and a photoreceptor that is installed at the first frame; a second assembly configured to include a second frame that is detachably combined with the first frame and a cleaning unit that is installed at the second frame and cleans a surface of the photoreceptor; at least one first pressing member configured to press the cleaning unit to the photoreceptor; and at least one second pressing member configured to press the cleaning unit into an opposite direction to a direction in which the first pressing member presses the cleaning unit.
Claims18
A photoreceptor cartridge comprising:
- a first assembly configured to comprise a first frame and a photoreceptor that is installed at the first frame;
- a second assembly configured to comprise a second frame that is detachably combined with the first frame and a cleaning unit that is installed at the second frame and cleans a surface of the photoreceptor;
- at least one first pressing member configured to press the cleaning unit to the photoreceptor;
- and
- at least one second pressing member configured to press the cleaning unit in an opposite direction to a direction in which the first pressing member presses the cleaning unit,
- wherein the second assembly is installed at the first assembly to pivot between a first position to clean the photoreceptor through the cleaning unit and a second position to separate the second frame from the first frame.
A photoreceptor cartridge comprising:
- a first assembly configured to comprise a photoreceptor;
- a second assembly configured to comprise a cleaning unit that cleans a surface of the photoreceptor and be detachably combined with the first assembly;
- at least one first pressing member configured to press the cleaning unit toward the photoreceptor;
- and
- at least one second pressing member configured to press the cleaning unit toward an opposite direction to a direction in which the first pressing member presses the cleaning unit, by using less pressure than pressure applied by the first pressing member,
- wherein the second assembly is installed at the first assembly to pivot between a first position to clean the photoreceptor through the cleaning unit and a second position to separate the second frame from the first frame.
An image forming apparatus comprising a photoreceptor cartridge:
- wherein the photoreceptor cartridge comprises:
- a first assembly configured to comprise a first frame and a photoreceptor that is installed at the first frame;
- a second assembly configured to comprise a second frame that is detachably combined with the first assembly and a cleaning unit that is installed at the second frame and cleans a surface of the photoreceptor;
- at least one first pressing member configured to press the cleaning unit to the photoreceptor;
- and
- at least one second pressing unit configured to press the cleaning unit toward an opposite direction to a direction in which the first pressing member presses the cleaning unit,
- wherein the second assembly is installed at the first assembly to pivot between a first position to clean the photoreceptor through the cleaning unit and a second position to separate the second frame from the first frame.
