ABSTRACT:
A cleaning device for use with an electrophotographic image forming apparatus has a charging brush positioned in contact with an endless image bearing surface of a rotatable image bearing member to form a contact region in which the brush provides an electric charge with a certain polarity to toner particles passing through the contact region according to a rotation of the image bearing member, and a cleaning member positioned on a downstream side with respect to a rotational direction of the image bearing member and in contact with the image bearing surface of the image bearing member to collect the toner particles from the image bearing surface. The charging brush has a base and a number of bristles planted in the base. A contact force of the charging brush against the image bearing surface is set to be more than 0 N/m and equal to or less than 1.5 N/m.
