Abstract
An image forming apparatus includes a housing, a registration roller pair, a first guiding portion, a second guiding portion, a resistor, and a grounding conductive mechanism. The housing is made of metal and has a grounded inner wall. The registration roller pair is located between the paper sheet feeder and the transfer member in the sheet conveyance path, includes a metallic registration roller and a facing roller that is constituted of an elastic material, and rotates in abutting contact with the registration roller, so as to convey the sheet toward the transfer nip portion. The first guiding portion is made of metal. The second guiding portion is made of a conductive resin material. The grounding conductive mechanism electrically conducts the registration roller, the first guiding portion, and the second guiding portion to the inner wall via a resistor.
