Abstract
An image forming apparatus includes an image forming unit, a first rotary member, a second rotary member, a web, a feed roller, a winding roller, a contact member, a detection unit, and a control unit. In a state where the apparatus is turned from a first power-ON state to a second power-ON state through a power-OFF state after the contact member reached a notch, if a difference between a diameter of a web at an end of the first power-ON state and the diameter of the web at a start of the second power-ON state is equal to or greater than a predetermined value, the control unit controls the image forming unit not to form a toner image. In the state after the contact member reached the notch, if the difference is smaller than the predetermined value, the control unit permits the image forming unit to form a toner image.
