Abstract
A cleaning unit, providable to an image carrier unit or an image forming apparatus, includes a cleaning member disposed in contact with a target member to electrically remove residual toner from the target member, an elastic blade disposed in contact with the target member upstream from the cleaning member, a blade supporting member, a blade power source, and a conductive member that is more conductive than the elastic blade, and electrically connects the blade supporting member and the elastic blade. The conductive member is disposed so that an edge part of the conductive member is closer to where the elastic blade contacts the target member than an edge part of the blade supporting member.
