A fixation apparatus for an electrostatic photographic copying machine.

摘要

A reat resistance bush is arranged between a heating roller and a bearing for supporting said heating roller, said heat resistant bush (31) and a gear (27) or sprocket fixedly mounted on said heating roller for revolving said heating roller being formed integrally from resin materials having a lower coefficient of thermal conductivity, an excellent heat resistance and the mechanical strength required for gears. Remarkably smaller noises are generated, a heating roller being able to be effectively heated, and an assembling operation also being easily achieved.
