Abstract
An image forming apparatus including an electrophotographic photoconductive member, a charging unit, a delivery unit and a cleaning unit. The charging unit is disposed in contact with the surface of the photoconductive member and the delivery unit disposed in contact with the surface of the charging unit. The delivery unit applies a layer of functional material to a surface of the charging unit and the charging unit in turn applies a layer of the functional material onto the surface of the photoconductive member. The cleaning unit is disposed in contact with a surface of the charging unit to clean the charging unit and reduce contamination of a surface of the delivery unit. The cleaning unit is disposed in an upstream direction of the delivery roller relative to a rotation direction of the charging unit.
