Abstract
An image forming apparatus includes a media roll, an image forming device, a conveyance unit, and a controller. In the roll, a printing medium having an adhesive face and no separation sheet on the adhesive face is wound in a roll shape. In pulling back the medium to the roll, the controller sets a linear velocity of the roll to be not lower than a linear velocity of a conveyance rotator of the conveyance unit. The controller controls a velocity difference between the roll and the rotator to be Va from a start of pulling back the medium to when a separation point of the medium from the roll reaches a tangent line of the roll in an area between the roll and the rotator. When the separation point reaches the tangent line, the controller switches the velocity difference from Va to Vb that is smaller than Va.
