A toner cartridge horizontally installed in an electrophotographic printer having a photoreceptor drum where an electrostatic latent image is formed by charging and exposure, and contributing to toner supply and development by being fixedly coupled to in the electrophotographic printer. The toner cartridge includes a housing filled with toner of a predetermined color, a development roller rotatably installed on the housing to face the photoreceptor drum and to supply the toner to the photoreceptor drum to develop an image by a difference in electrical potential, a supply roller rotatably installed in the housing in contact with the development roller and to control the toner to adhere to the development roller, and a guide member coupled to the housing to be disposed under the supply roller and to guide supply of the toner. When a diameter of the development roller is D2, the diameter D2 satisfies an inequality that 10.4≦D2≦22.1 mm.

A process cartridge, which uses a removable cartridge and also a one-property contact system, used with an image forming apparatus, includes a drum cartridge in which a photoconductive drum is disposed in an exposed manner, a toner cartridge in which a developing roller rotating in contact with the photoconductive drum is mounted in an exposed manner, and supporting members supporting and guiding the toner cartridge so that the developing roller moves linearly with respect to the photoconductive drum. The supporting members are made stationary in predetermined positions of the main body, and a developing nip between the photoconductive drum and the developing roller is controlled as the toner cartridge is moved linearly with respect to the supporting member within a predetermined distance range.

A controllable clutch includes a plurality of piston members, a plurality of oil passages communicating with the piston members and a plurality of grooves for receiving a roller from the piston members. The piston members are disposed in one of an inner race and an outer race. The pistons in the piston member can extend in the same rotational direction to form a one-way clutch in that direction. Alternatively, the pistons in the piston members can extend in opposite rotational directions to form a clutch. Or, by selectively applying hydraulic fluid to the piston members, a one-way clutch can selectively be formed in either rotational direction.

A process cartridge unit and an image forming apparatus having the same. The image forming apparatus includes a main body, a process cartridge unit removably mounted in the main body, an opening provided in the main body to permit the process cartridge unit to be installed or removed, and a cover rotatably mounted to the main body so as to expose or shield the opening. The process cartridge unit includes a container to store a developer and at least one knob coupled to the container. When the cover is closed, the knob is folded by the cover, and when the cover is opened, the knob is unfolded. Accordingly, since the position of the knob is changed, a mounting space of the process cartridge unit can be decreased, and a user can easily grasp the knob.
