<P>PROBLEM TO BE SOLVED: To provide an electrophotographic process unit provided with a toner sealing structure which hardly causes toner leakage without imparting strong pressing force to the peripheral surfaces of both end parts of a developing roller, then, enables an inexpensive motor having low torque to be used. <P>SOLUTION: In the electrophotographic process unit provided with the toner sealing structure where the developing roller feeding toner to the surface of a photoreceptor while being rotated is fixed to a frame body disposed so as to be opposed to the peripheral surfaces of both end parts of the roller and which is pressed by and is brought into slidable contact with a napped sealing member 9b provided with ground fabric 9b-3 and a napped fiber group 9b-1 to which hair fall-down working is performed, the napped sealing member 9b is fixed to the frame body so that an assumed cross angle 7c between the hair fall-down direction C of the napped fiber group 9b-1 and the rotating direction A of the developing roller 7 is set so as to make the direction of force that the toner receives by the napped fiber group and the rotation of the roller coincide with a direction including axial direction moment directed in the center part direction of the roller. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
