PROBLEM TO BE SOLVED: To provide an electrophotography type image forming device capable of forming a laminate sheet without making the surface dirty with a toner. SOLUTION: A laser printer has a transfer roller to which a transfer bias is applied in order to transfer a toner image formed on a photosensitive drum to a recording form and a control unit for controlling the applying of the transfer bias. The control unit controls so that in the case that a laminate forming mode is selected with a panel switch, while a laminate sheet member passes through between a photosensitive drum and the transfer drum t23-t32, forward bias and backward bias are not applied to the transfer roller, and the transfer roller is kept in a no-bias state. The laminate sheet member is carried without being transferred with the remaining toner on the photosensitive drum or the transfer roller, heated and pressed in a fixing unit, and a laminate sheet with no dirt by the toner is prepared. |
