Abstract
An image forming apparatus includes: an image carrier having a first rotation axle, a charging roller having a second rotation axle, a conductive member to contact a surface of the image carrier, a gap size acquisition device, and a gap adjustment device. The charging roller is disposed adjacent to the image carrier in a non-contact manner across a gap to charge the image carrier. The gap size acquisition device acquires a size of the gap. The gap adjustment device adjusts a distance between the first rotation axle and the second rotation axle based on information from the gap size acquisition device to maintain the size of the gap within a predetermined range.
