A toner hopper which is arranged upwards of the developing unit is elevatably supported in the image forming device in the vertical direction thereof. Therefore, as the connection thereof with the developing unit can be cancelled by lifting up the toner hopper when drawing out the developing unit, the structure of the connection portion therebetween can be simplified and the sliding portion can be eliminated, thereby causing the troubles due to wearing at the connection therebetween to be eliminated. Simultaneously, it is possible to provide means for automating the elevation and lowering of the toner hopper and means for maintaining the horizontality of the toner hopper when being elevated and lowered.
