ABSTRACT:
A photoconductive drum has a flexible photoconductive loop and an expandable mount. The mount includes a shell with a slit allowing the shell to expand. A pair of wedges are moved toward each other on a shaft. Cam surfaces on the wedges push against chamfered corners on ribs extending inward from the shell to expand both ends of the shell. The shell assumes the shape of the loop even though loop is slightly conical.
