<p>PURPOSE:To widen the usable paper quality range by surely separating an attracted photosensitive paper from a photosensitive drum and separating the paper from a transport roller by installing a photosensitive paper separating means and attracting means which communicates to a duct, on a transport roller having a vacant hole and a plurality of air holes. CONSTITUTION:On a paper transport roller 3 which revolves at the equal peripheral speed to the peripheral speed of a photosensitive drum 1 and acts to separate a paper sheet which is attracted on the drum 1, a plurality of air holes 3b which penetrate from the inner peripheral surface to the outer peripheral surface of a vacant hole 3a are formed. The ozone which is generated on the periphery of the photosensitive body drum 1 is discharged outside, and an attracting means (ozone discharge fan 6 and a duct 9) for attracting air from the vacant hole 3a of the paper transport roller 3 through the air holes 3b is installed. Further, a separating hook 4 for separat ing the paper which is separated from the surface of the photosensitive body drum 1 and attracted on the paper transport roller 3 is installed, and the paper is introduced into an ordinary paper transport passage. With this constitution, the trouble such as paper clogging is eliminated, and the need of using the rigid paper is obviated.</p> |
