Abstract:
A cleaning device includes a cleaning member, a collection member, an electrical field generator, and a separation member. The cleaning member has a surface capable of moving while contacting a surface of a cleaning target to remove toner on the surface of the cleaning target. The collection member has a surface capable of moving while contacting the surface of the cleaning member to collect the toner on the surface of the cleaning member. The electrical field generator generates an electrical field to move the toner from the cleaning member to the collection member. The separation member contacts the surface of the collection member to separate the toner on the surface of the collection member. The collection member has a centerline average surface roughness of not more than 0.1 μm and shows a surface hardness rank of B or higher in a steel-wool scratch test.
