Heat fixing unit in an electrophotographic copying apparatus

摘要

A heat fixing unit in an electrophotographic copying apparatus is disclosed. The heat fixing unit comprises a heat fixing roller with a heater, a pressure roller with a plurality of fibers, and driven ring components disposed on the ends of the pressure roller for adjusting the contact amount between the heat fixing roller and the pressure roller. The heat fixing unit offers a less warming up time and a better paper delivery performance, and requires less material cost. The heat fixing unit in an electrophotographic copying apparatus may employ a fixed type or a rotary type curing unit for raising the plurality of fibers.
