    摘要: An image forming apparatus includes an image bearing member are a plurality of developing units for developing electrostatic latent images formed on the image bearing member with different color images. A rotatable developing rotary supports the plurality of developing units, which are detachably movable to the rotary member. A heat fixing device fixes the toner on a recording material after the toner image is transferred onto the recording material from the image bearing member. A controller executes, an intermittent rotating operation, before the image forming apparatus is brought into a stand-by state, when a fixing temperature of the fixing device is lower than a predetermined level.

    摘要: A developer supply container for supplying a developer for developing a latent image formed on a photosensitive member is provided, wherein the container is inserted into a developer accommodating container which is provided in a process cartridge, through an entrance opening, and the developer is supplied while the container is in the developer accommodating container, and wherein the entrance opening is covered by an openable cover, and wherein when the developer supply container is mounted and demounted, the openable cover is opened, the developer accommodating container being usable with an electrophotographic image forming apparatus. The developer supply container includes a developer accommodating portion for accommodating the developer; a supply opening for supplying the developer accommodated in the developer accommodating portion to the developer accommodating container; a seal member for openably sealing the supply opening; a closing member for closing the openable cover, while the developer supply container is mounted in the developer accommodating container, wherein when the developer supply container is not mounted in the developer accommodating container, the openable cover is not closable.

    摘要: A solenoid of an electromagnetic clutch includes an annular coil, an annular coil housing which covers a radially facing outer peripheral surface, a radially facing inner peripheral surface and an axially facing end face of the coil. An armature is adapted to be attracted to the one end face of the coil housing by supplying an electric current to the coil. The housing axially protrudes past the other axially facing end face of the coil by a distance L. Thus, the magnetic resistance around the outer periphery of the coil is decreased to enhance the magnetic flux density of the magnetic closed circuit, thereby enabling the reliable attraction of the armature without increasing the electric power consumed by the coil.
