Patent ID: 7593677

Claim:
An image forming apparatus comprising: a rotatable belt member for bearing a toner image; a first transfer member, which is grounded and abuts an outer peripheral surface of the belt member; a second transfer member, which abuts an inner peripheral surface of the belt member and presses the first transfer member through the belt member so as to form a transfer portion, where a toner image borne on the belt member is transferred to a transfer material; a first voltage output portion, which applies a voltage having a same polarity as the toner to the second transfer member; a first bending member, which is arranged downstream of the transfer portion in a rotating direction of the belt member, abuts the outer peripheral surface of the belt member and bends the belt member toward the inner peripheral surface of the belt member; a second bending member, which is grounded, abuts the inner peripheral surface of the belt member and presses the first bending member through the belt member; and a second voltage output portion, which applies a voltage having a same polarity as the toner to the first bending member.
