摘要： 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.

摘要： 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.

摘要： 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.

摘要： An image-forming device includes: a main body; at least one photosensitive member; a plurality of developing units; a transferring unit; a first holding unit; and a guiding unit. The photosensitive member has a support shaft. Each developing unit has a developer-accommodating section that accommodates developer. The developer-accommodating section has an opening in a top side thereof. Each developing unit further has a developer-carrying member that is disposed near the opening of the developer-accommodating section. The first holding unit holds the plurality of developing units that are arranged in a row along a first removal direction. The first removal direction is orthogonal to the support shaft of the photosensitive member. The first holding unit is accommodated at a first accommodating position in the main body. The guiding unit enables the first holding unit to move between the first accommodating position and a first removal position that is separate from the first accommodating position in the first removal direction.
