The device includes a pair of fixing rollers provided at a position separated by a predetermined interval from a photosensitive drum, a tractor unit, a feed sensor, a tip sensor, and a control unit. The tractor unit is provided between the fixing rollers and the photosensitive drum to feed the continuous form toward the fixing rollers, the feed sensor outputs feed pulses in accordance with an amount fed of the continuous form, the tip sensor senses the tip portion of the continuous form. The control unit counts the number of feed pulses sensed by the feed sensor to feed one page of the continuous form so as, to discharge one page from the outlet mouth of the printer when a positioning of the tip portion is needed.Other References
