ABSTRACT:
An electrostatic printing apparatus of the pressure fixing type having a toner image formed on a recording sheet fixed by applying pressure, including a tension imparting device for imparting to the recording sheet a tension oriented in the direction of travel of the recording sheet and a tension oriented in a direction perpendicular to the direction of its travel, and a regulating device for regulating the angle and posture of the recording sheet located in the path of movement of the recording sheet immediately before a pressure fixing roller device. The recording sheet is kept in taut condition as it is fed to the pressure fixing roller device to enable wrinkling, jamming and skewing of the recording sheet to be avoided.
