Claim:
1. An image forming apparatus, comprising: a toner image forming unit configured to form a toner image on a surface of an image bearer; a nip formation member configured to contact the surface of the image bearer to form a transfer nip; a transfer power source configured to output a transfer bias to transfer the toner image from the image bearer onto a recording sheet in the transfer nip; an information acquisition device configured to acquire specific information that specifies whether the recording sheet as a transfer target of the toner image is an uneven surface sheet having an uneven surface; and a controller configured to output a bias including a superimposed voltage, in which an alternating current (AC) voltage is superimposed on a direct current (DC) voltage, as the transfer bias from the transfer power source when the specific information acquired by the information acquisition device is not information corresponding to the uneven surface sheet and to output a bias including only the DC voltage as the transfer bias from the transfer power source when the specific information is the information corresponding to the uneven surface sheet.
