Abstract:
An image forming apparatus fixes a toner image on a transfer material at a fixing portion by applying an AC voltage from an AC power source to a fixing unit and includes a conductive pre-transfer guide on a position at which the transfer material nipped by a transfer portion and the fixing portion is in contact therewith. A capacitor and a Zener diode which is connected to the capacitor in parallel and maintains the pre-transfer guide at a predetermined voltage in a state in which a toner image is transferred to the transfer material nipped by the fixing portion and the transfer portion are arranged between the pre-transfer guide and the ground.

Claim (Index 1):
An image forming apparatus comprising:\n an image bearing member configured to bear a toner image; a transfer member configured to form a transfer portion by abutting on the image bearing member and transfer a toner image born by the image bearing member to a transfer material at the transfer portion; a fixing unit which is disposed on a downstream side than the transfer member in a conveyance direction of the transfer material and includes a heating member configured to heat the transfer material and a pressing member configured to form a fixing portion by being in contact with the heating member and to fix the toner image to the transfer material nipped by the fixing portion by being applied with an alternate current (AC) voltage; a conductive member arranged on an upstream side of the fixing portion in the conveyance direction of the transfer material and on a position at which the transfer material nipped by the transfer portion and the fixing portion is in contact thereto; a capacitor disposed between the conductive member and ground; and a constant voltage element which is connected to the capacitor in parallel and is maintained at a predetermined voltage on a side connected to the conductive member in a state in which the toner image is transferred to the transfer material nipped by the fixing portion and the transfer portion.
