ABSTRACT:
An image forming apparatus having a structure in which it is judged whether or not the trailing end of a continuous sheet is fixed to a feeding reel. The continuous sheet wound around the feeding reel is pulled out, and is conveyed through a conveying path passing through an image forming section. When the continuous sheet is conveyed, the rotation or the stop of the feeding reel is detected. When the stop of the rotation of the feeding reel is detected while the continuous sheet is being conveyed, it is judged that the continuous sheet has been used up. The continuous sheet is further conveyed for a predetermined time period after the judgment. It is judged whether or not the trailing end of the continuous sheet is fixed to the feeding reel depending on whether or not the continuous sheet exists in a predetermined position of the conveying path.
