Abstract:
    An image forming apparatus including an image forming unit to form a developer image on an image carrier, a conveying member to convey an image receiving member toward the image carrier, a transfer charger to transfer the developer image formed on the image carrier on the image receiving member by giving a transfer charge to the image receiving member conveyed by the conveying member, a guide member provided to guide the image receiving member, and a separation charger to separate the image receiving member with the developer image transferred thereon by the transfer charger. A bias voltage having the same polarity as the transfer charge is applied to the guide member. When the developer image is transferred on the image receiving member by the transfer charger, this bias voltage is controlled so that it is set at a first bias voltage before the image receiving member comes near the separation charger and at a second bias voltage that is larger than the first bias voltage when the image receiving member comes near the separation charger.
