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 161 and wire power-feed electrodes 162 are attached to a slide frame 140. Each of the developing electrode members 161 has a first body-side contact 161e3. The developing electrode members 161 are electrically connected with developing-roller output terminals 171 through contact with the developing-roller output terminals 171. The wire power-feed electrodes 162 are electrically connected with wire output terminals 172 through contact with the wire output terminals 172. The developing electrode members 161 are elastically deformed as a result of their first body-side contacts 161e3 being pressed in an M2 direction, which is along a slide direction S, by the developing-roller output terminals 171. The wire power-feed electrodes 162 are pressed in a paper width direction by the wire output terminals 172.
