Electro-photographic printing apparatus comprising a toner fixing unit

Abstract

A fixing unit of an electro-photographic apparatus having: a heat roller installed on a frame, for fixing a toner image on a sheet; a pressure roller for pinching the sheet with the heat roller; a separator contacting the heat roller, for separating the sheet from the heat roller; a cleaning wiper contacting the heat roller, for cleaning the heat roller; and a sub-frame carrying the pressure roller, the separator and the cleaning wiper, where the sub-frame is hinged by an axle which is installed on the frame, in parallel to the heat roller. The pressure roller, the separator and the cleaning wiper are released all together from the heat roller when the sub-frame is opened by being rotated around the axle. In thus-opened state, the jammed sheet can be easily taken out by operator's finger because the jammed sheet is exposed to thus-provided sufficiently wide space and the sheet is merely sticking to heat roller without being undesirably bitten by separator 16 or by cleaning wiper 17. Moreover, the easy sheet-removal operation prevents the operator's fingers from being burnt by touching the hot heat roller.
