ABSTRACT:
An image forming apparatus includes an image bearing member, image forming device for forming an image on the image bearing member, a transfer charger for transferring the image formed on the image bearing member by the image forming device onto an image receiving member, the transfer charger including a transfer member contacted to the image bearing member and voltage application source for applying a voltage to the transfer member to transfer the image from the image bearing member to the image receiving material, wherein the voltage which is applied to the transfer member from the voltage application source at least during image transfer action by the image transfer charger, is lower than a charge starting voltage of the transfer member between itself and the surface of the image bearing member.
