摘要： An image formation unit that forms an image on a transfer medium, a conveyance unit that conveys the transfer medium, a control unit that controls formation of the image and conveyance of the transfer medium are provided. The control unit has a sheet gap image forming function of forming a predetermined toner image in a sheet gap between the transfer media conveyed by the conveyance unit. When the transfer medium is conveyed, the control unit acquires information of a tilt angle on a conveyance surface of the transfer medium conveyed to the image formation unit, calculates a sheet gap between the transfer media based on the tilt angle, determines whether or not a toner image of a required amount is able to be formed in the sheet gap when performing the sheet gap image forming function, and controls formation of the sheet gap image based on the determination result.
