ABSTRACT:
An electrostatic recording apparatus for recording, developing and fixing an image on a sheet of recording paper includes an electrostatic recording head and a roller for forming an electrostatic image on the sheet of recording paper while the latter travels between the electrostatic recording head and the roller. The electrostatic recording head and the roller are relatively movable toward each other for pressing the sheet of recording paper against the electrostatic recording head during a period of time in which the sheet of recording paper travels between the electrostatic recording head and the roller to allow the electrostatic recording head to form the electrostatic image on the sheet of recording paper. The electrostatic recording head and the roller are relatively displaceable away from each other during a period of time other than the above period of time. The roller has a first portion which rotates whenever a sheet of recording paper passes between the recording head and the roller, and a second portion which rotates only when a sheet of paper having a predetermined width passes between the recording head and the roller.
