ABSTRACT:
A cleaning seal with a soft cleaning seal tip provides a seal between the cleaning housing and the photoconductive member in an electrophotographic machine. The cleaning seal is made of a relatively stiff material so that the cleaning seal can collect and support the toner removed from the photoconductive member. In the absence of the soft cleaning seal tip, the relatively stiff material of the cleaning seal contacting the photoconductive member excessively scratches the photoconductive member. The soft cleaning seal tip solves this problem by providing a relatively soft surface on the photoconductive member, resulting in fewer scratches on the photoconductive member. The composite cleaning seal provides the sufficient force to remove and support the toner removed from the photoconductive member while cushioning the force of the relatively stiff cleaning seal against the photoconductive member.
