Abstract:
1. An image processing apparatus, comprising: a heat roller configured to have a roller surface for contacting a medium on which an unfixed toner image is transferred; a press roller configured opposite to the heat roller; a guide configured along a conveyance space from an inlet arranged at a downstream side in a conveyance direction of the medium, which is conveyed and nipped by the heat roller and the press roller, to an outlet of the medium; a lever configured to be provided with a swing shaft with respect to the guide, a peeling claw arranged at the inlet side for scraping the toner off the roller surface, and a lever end positioned at the outlet side; a swing section configured to swing and energize the lever to make the lever end protrude into the conveyance space, wherein the lever that is swung and energized by the swing section repeats the following operations: separating the peeling claw in a contacted state with the roller surface from the roller surface, and restoring the peeling claw to the contacted state; a pair of paper discharge rollers configured at the outlet side of the guide to rotate forward or rotate backward; and a reversal guide configured to be provided with a guide bottom for receiving the medium switched back and conveyed by turning the medium upside down through the backward rotation of the pair of paper discharge rollers, wherein if the rear end of the medium passes through the lever end during the forward conveyance prior to the switchback conveyance, the lever end restores to the protruding position at the upper portion, and during the switchback conveyance, the rear end of the medium jumps through a lifting force of the lever end at the protruding position, and the rear end is guided to the reversal guide while it is in non-contact with the end portion of the guide bottom.
