Abstract:
1. An image forming apparatus, comprising: a media roll in which a printing medium having an adhesive face and no separation sheet on the adhesive face is wound in a roll shape; an image forming device to form an image on the recording medium; a conveyance unit including a conveyance rotator to convey the printing medium; and a controller to control the conveyance rotator and the media roll to rotate in reverse and pull back the printing medium to the media roll, in pulling back the printing medium to the media roll, the controller sets a linear velocity of the media roll in a rotation direction of the media roll to be not lower than a linear velocity of the conveyance rotator in a rotation direction of the conveyance rotator, wherein the controller controls a velocity difference between the linear velocity of the media roll and the linear velocity of the conveyance rotator to be Va from a start of pulling back the printing medium to when a separation point of the printing medium from the media roll reaches a tangent line of the media roll in an area between the media roll and the conveyance rotator, and wherein, when the separation point of the printing medium reaches the tangent line of the media roll, the controller switches the velocity difference from Va to Vb that is a smaller velocity difference than Va.
