    Abstract: A process cartridge is configured to be mounted in an apparatus main body along a predetermined mounting direction. The process cartridge includes: a photosensitive drum; a drum drive input member into which a driving force for rotating the photosensitive drum is inputted; and a frame which holds the photosensitive drum and the drum drive input member; the frame including: a substantially cylindrical first protecting member which is formed on the frame. The first protecting member is configured to accommodate the drum drive input member, and project in a rotational axis direction of the photosensitive drum, wherein a projecting amount of a portion of the first protecting member which lies at a downstream side in the mounting direction is smaller than a projecting amount of a portion of the first protecting member which lies at an upstream side in the mounting direction.

    Abstract: A system that provides a compact and functional image forming device that can securely supply a driving force to the developing cartridge is described. A developing cartridge is described that can be mounted to the image forming device in an insertable/removable manner. A passive coupling gear and cylinder externally project in the width direction of the collar member allowing secure supply of a driving force through connection of the passive coupling gear to the coupling input shaft. In addition, the amount of movement of the coupling input shaft to connect with the passive coupling gear can be minimized, thereby allowing for a miniaturization of the color laser printer. Furthermore, in addition to the original function, the function of being guided by the left guiding groove for the passive coupling gear and the function of being guided by the right groove for the cylinder can be added.

    Abstract: When a developer cartridge is mounted together with a drum unit in a main body casing, a detection gear is rotated by driving of a motor, and an abutment projection of the detection gear is brought into abutment against a lever of a drum subunit to move the lever. The movement of the lever is detected by an optical sensor. A CPU judges information on the developer cartridge on the basis of the results of the detection by the optical sensor. Therefore, the information on the developer cartridge can be judged with a simple construction at reduced costs. Further, the developer cartridge can be mounted in the main body casing in spaced relation, so that the design flexibility is increased.

    Abstract: A developer cartridge includes a developer roller, a support member and a first seal member. The developer roller has a rotational axis and a peripheral surface. The peripheral surface includes a center zone and an end zone at one end portion in an axial direction. The support member supports the developer roller to be rotatable about the rotational axis. The support member has an opposing surface opposed to the end zone. A protrusion protrudes from the opposing surface, and extends in a direction crossing with the axial direction. The first seal member is disposed between the end zone and the opposing surface in order to prevent developer from leaking out of a space formed between the end zone and the opposing surface.
