<P>PROBLEM TO BE SOLVED: To efficiently supply powder developer to a developing roller side. <P>SOLUTION: The image forming unit 11 is an electrophotographic type one, and forms an image on the outer peripheral surface of a photoreceptor drum 12 with toner supplied from the developing roller 15. A casing 16 in which the roller 15 is housed can be displaced while rocking with a rocking shaft 23 as center so that pressing force to the outer peripheral surface of the drum 12 by the roller 15 can be adjusted. Toner is stored in a developer tank 17, fed in a toner feeding tube 21 by a screw 22 and supplied into the casing 16 from the position of the shaft 23. The toner is efficiently carried to the position of the tube 21 by rotating a trapezoidal blade in the tank 17 whose inner space is columnar. <P>COPYRIGHT: (C)2003,JPO |
