Besides, halogen heaters 19 that dry the image formed on the continuous feed paper P are disposed around the drying drum 18. The halogen heaters 19 dry the image on the continuous feed paper P wrapped around the drying drum 18.

The image forming unit 11 is provided with a control mechanism 20 that controls the various members. The control mechanism 20 includes a central processing unit (CPU), a read only memory (ROM), a random access memory (RAM), and other storage devices such as a hard disk device (none of which are illustrated).

The pre-processing unit 12 includes a supply roller 12A around which the continuous feed paper P to be supplied to the image forming unit 11 is wrapped. The supply roller 12A is rotatably supported by a frame member (not illustrated).

On the other hand, the post-processing unit 14 includes a winding roller 14A as an example of a transport portion that winds the continuous feed paper P on which an image has been formed. The winding roller 14A is rotationally driven by a motor (not illustrated). When the winding roller 14A is rotated, the continuous feed paper P is drawn out from the supply roller 12A, and transported along the transport path 16. The transport speed of the continuous feed paper P is controlled by the control mechanism 20. Specifically, the rotational speed of the motor (not illustrated) which rotationally drives the winding roller 14A is controlled by the control mechanism 20.
