ABSTRACT:
A sealing roller for preventing toner particles from inadvertently soiling the inside of an electrostatic copying machine. The sealing roller is placed in rolling contact with the photoconductive surface and seals the gap between that surface and the residual particle cleaning device housing. Any particles that are not removed by the cleaning device are therefore prevented from escaping and soiling the machine.
