Abstract
An image forming apparatus includes an image carrier, a transfer unit, and a control unit. The image carrier has a surface to bear a toner image thereon. The transfer unit has a transfer member to transfer the toner image onto a recording sheet conveyed in a conveyance direction for trailing-end borderless image formation and duplex image formation. The transfer unit is configured to form the toner image on the recording sheet without forming a margin at a trailing end of the recording sheet in the conveyance sheet in the trailing-end borderless image formation. The transfer unit is configured to form the toner image on front and back faces of the recording sheet in the duplex image formation. When a width of the toner image formed in a borderless image area of the recording sheet in the trailing-end borderless image formation is smaller in a direction perpendicular to the conveyance direction than a threshold value, the control unit permits the duplex image formation. When the width is the threshold value or greater, the control unit prohibits the duplex image formation.
