Abstract
In the case that recording paper of a roll (20) has run out during an image forming process, when the length of a piece of the remaining recording paper left last is longer than the first reference length possible to feed the paper in the inside and outside of a roll unit (RU), the paper is delivered, and when the length of the remaining piece is slightly shorter than the first reference length, the front end of the remaining piece is projected to the outside of the roll unit (RU), and when the length of the remaining piece is shorter than the second reference length impossible to feed the paper in the inside of the roll unit (RU), the remaining piece is dropped inside of the roll unit (RU) by a reverse feeding, thereby, a removal of the remaining piece is facilitated. Thus, the removal of the remaining piece may always be performed well.
