Abstract
Multicolor electrophotographic apparatus secures the ends of a receiving sheet in a trough which runs parallel to the axis of rotation of a transfer roller. An inclined surface in the trough gradually declines the transfer sheet away from the periphery of the transfer roller to prevent a photoconductive drum 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.
