发明名称 MULTICOLOR IMAGE FORMING APPARATUS AND TRANSFER ROLLER
摘要 <p>Multicolor electrophotographic apparatus secures the ends of a receiving sheet in a trough (45) which runs parallel to the axis of rotation of a transfer roller (11). An inclined surface (51) in the trough gradually declines the transfer sheet away from the periphery of the transfer roller to prevent a photoconductive drum (1) from receiving a jar as it rides off the edge of the transfer sheet. Preferably, the means defining the declining ramp surface also defines vacuum holes for securing the ends of the receiving sheet.</p>
