Image forming apparatus

摘要

An image forming apparatus comprising: an image recording unit including image carriers on which toner images are respectively formed, a paper carrier which conveys paper fed to a paper drawing-in position while drawing therein, and transfer units which transfer respective toner images on the image carriers onto the paper on the paper carrier at predetermined image transfer positions of the image carriers; paper jam detecting means for detecting a paper jam occurring when the paper drawn in by the paper carrier adheres to the surfaces of the image carriers; conveyor rollers disposed in a paper feeding unit which feeds the paper to a paper drawing-in position in the image recording unit at a predetermined timing; an inlet chute including an upper paper guide and a lower paper guide for guiding the paper fed from the conveyor rollers toward the paper drawing-in position; conveyor roller rotation control means which suspend the rotation of the conveyor rollers until the paper stretched between the image recording unit and the conveyor rollers of the paper feeding unit has passed through the conveyor rollers, if a paper jam arises while the paper is stretched between them; reverse rotation suspending means which rotates the paper carrier in a reverse direction if a paper jam arises and then suspends the rotation; and a removable member configured so as to be detachable from, and attachable to, a main unit of the image forming apparatus.
