Abstract:
An image forming apparatus comprising:image forming means for forming a developer image on an image carrier;conveying means for conveying an image receiving member toward the image carrier;transfer means for supplying a transfer charge to the image receiving member conveyed by the conveying means and transferring the developer image formed on the image carrier to the image receiving member;a guide member, provided between the conveying means and the transfer means, for guiding the image receiving member conveyed by the conveying means toward the transfer means;separation means, arranged at the downstream side of the transfer means along the transfer direction of the image receiving member, for supplying a separation charge to the image receiving member to separate the image receiving member having the developer image transferred by the transfer means from the image carrier;applying means for applying a bias voltage of the same polarity as the transfer charge to the guide member; andcontrol means for controlling the applying means to apply a first bias voltage to the guide member when a part of the image receiving member receives only the transfer charge from the transfer means and a remaining part of the image receiving member is put on the guide member, and for controlling the applying means to apply a second bias voltage larger than the first bias voltage when a part of the image receiving member receives both of the transfer charge and the separation charge from both of the transfer means and separation means and a remaining part of the image receiving member is put on the guide member.
