Abstract
A developing device includes a developing roller and a conductive member. The rotatable image developing roller feeds a one-component toner to an image forming drum. The developing roller is in contact with the linearly shaped conductive member. A voltage is applied to the developing roller, while a second, higher voltage is applied to the conductive member. The two voltages are of the same polarity. This arrangement makes it possible to control component aggregation on the developing roller and eliminate any image/non-image potential difference on the image carrier.
