Abstract: PURPOSE:To enable sheets to be positively separated one by one and transferred while its tip end is not folded and damaged by providing a sheet stopper which moves to a stop position from an evacuation position when the pressure contact of a separating device is released. CONSTITUTION:A sheet stopper 29 is in No.1 evacuation position which is located on the transfer side of a sheet S rather than the pressure contacting position side while a separating roller 26 is pressing with pressure so as to allow the sheet S to be frictionally separated. Then, when the separating roller 26 is separated from a separating belt 25 while a link 27A and 27B is pulled by a solenoid 28, the tip end 29A of the sheet stopper 29 is pushed by the link 27A allowing it to be rotated clockwise. This allows the sheet stopper to move to No.2 stop position which is located on the side of a sheet setting table rather than the pressure contacting position side. At this stop position, the lower end surface 29B of the sheet stopper 29 holds the tip end of following sheet groups with exception of the sheet S1 preventing them from passing through underneath the separating roller 26.

Title: Electrophotographic device having plural developing unit
Inventor: SENBA HISAAKI
IPC: G03G15/08
Filed: 1985-03-14
Abstract: PURPOSE:To obtain a sufficient image density after leaving a developing unit for a long period of time by constituting such that all developing units can abut when the photosensitive body is inoperable (non-rotation). CONSTITUTION:The developing units 4 and 5 can move in a space covering the state where they abut on the surface of the photosensitive body 1 and the separate state several mm away from said state by means of eccentric cams 9 and 10 and other mechanisms. The photosensitive body has a heating source 11 in its inside, and is always conductive irrespective of turning on and off of a main switch and temperature-adjusted by a temperature adjusting element, for instance, a thermyster. The heating source 11 prevents the moisture absorption of the sensitizing material, and acts as preventing the drop in the resistance of the photosensitive body and the disturbance of an electrostatic latent image due to the drop. Thus each developing unit can obtain a stable image density after it is stopped for a long period of time.
