Abstract: 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.
