Abstract: A toner hopper which is arranged upwards of the developing unit is elevatably supported in the image forming device in the vertical direction thereof and the connection between the toner hopper and the developing unit can be cancelled by lifting up the toner hopper when drawing out the developing unit so that the structure of the connection portion therebetween can be simplified and the sliding portion can be eliminated to thereby eliminate wearing at the connection therebetween. Furthermore, an apparatus for automatically raising and lowering the toner hopper and an apparatus for maintaining the horizontality of the toner hopper when being elevated and lowered is provided.

Abstract: A copying paper feeding device for an intermediate tray for use in a copying machine having functions of creating a copy on both sides of a paper or printing a compound copy. In the device while being pressed by a push-out roller, copying papers fed into the intermediate tray are delivered by the rotation of the push-out roller in the direction of a copying paper aligner located downstream and upper-positioned copying papers are pushed out a little further than lower-positioned copying papers in response to a counted number of copying papers fed into the intermediate tray.
