Image forming apparatus

摘要

The present invention provides a configuration in which an electrically connected condition can further be stabilized in electrical-connection zones between a body of an image-forming apparatus, and an image-forming unit and a plurality of image-forming cartridges. Developing electrode members and wire power-feed electrodes are attached to a slide frame. Each of the developing electrode members has a first body-side contact. The developing electrode members are electrically connected with the developing-roller output terminals. The wire power-feed electrodes are electrically connected with wire output terminals through contact with the wire output terminals. The developing electrode members are elastically deformed as a result of their first body-side contacts being pressed in a direction, which is along a slide direction, by the developing-roller output terminals. The wire power-feed electrodes are pressed in a paper width direction by the wire output terminals.

主权项

1. An image-forming apparatus comprising:
a main body including a body electrode; a cartridge including a developing roller and a cartridge electrode, the cartridge electrode being electrically connected with the developing roller; and a slide frame movable relative to the main body along a slide direction, wherein the slide frame further comprises:
a side frame; andan electrode mounted to the side frame, the electrode comprising:
a first terminal portion configured to establish an electrical connection with the cartridge electrode; anda second terminal portion comprising a coil spring portion, wherein the coil spring portion further comprises:
a first sub coil spring mounted to the side frame,a second sub coil spring mounted to the side frame, anda body contact provided between and spacing apart the first sub coil spring and the second sub coil spring, the body contact being configured to contact the body electrode when the slide frame is at a position within the main body.
