An electrophotographic image forming apparatus is provided to install a device comprised of a busing, a second elastic member, and a holder in an end portion of an opposite side of a rotary roller so as to press the rotary roller in the same direction as a direction of a first elastic member of a high voltage power supply, thereby simplifying the structure of the high voltage power supply and improving the productivity and assembly of a single product, and reducing production cost. An electrophotographic image forming apparatus comprises a rotary roller, a high voltage power supply, a frame, and an elastic member(131). The rotary roller has a rotation shaft made of a conductive material. The frame supports the rotary roller. The elastic member is interposed between the frame and the rotary roller to press the rotary roller elastically in a predetermined direction, contacts the rotation shaft of the rotary roller to receive the high voltage of the high voltage power supply, and transmits the high voltage to the rotation shaft. |
