Abstract
An image forming apparatus includes a transfer brush for transferring to a paper sheet a developed image on an photoconductive drum. The transfer brush is formed in a plate-like shape by a number of electroconductive fibers bundled together. The transfer brush has a contact portion set in elastic contact with the drum. The brush presses the paper sheet, which is fed by the feeding device, against the drum under a predetermined pressing force. A DC current supply applies voltage to the paper sheet through the transfer brush so as to electrostatically attract the developed image to the paper sheet. The transfer brush is inclined to the image carrier so as to allow the paper sheet to be guided into an area between the drum and the transfer brush.
