ABSTRACT:
An image recording apparatus according to the present invention has a photosensitive drum, a pre-transfer roller, and a fixing roller. The photosensitive drum, the pre-transfer roller and the fixing roller are generally rotated at an equal peripheral speed. Particularly, the peripheral speed of the photosensitive drum and the peripheral speed of the fixing roller are equal to each other, whereby there is no problem that an image transferred to a rolled-paper sheet from the photosensitive drum extends due to the leading end of the rolled-paper sheet being pulled after reaching the fixing roller. On the other hand, after the leading end of the rolled-paper sheet reaches the fixing roller, the peripheral speed of the pre-transfer roller is so controlled as to be lower than the peripheral speed of the photosensitive drum during a predetermined time period. Suitable tension can be applied to the rolled-paper sheet leading to the fixing roller from the pre-transfer roller by such control as to decrease the peripheral speed of the pre-transfer roller. The rolled-paper sheet is not made slack and is not jammed at the time of conveyance if suitable tension is applied thereto.
