Abstract

An electrostatographic apparatus has a driving roller, a tension roller, a belt-like recording medium that moves over the roller in an endless track manner, an ion head that forms an electrostatic image on the surface of the recording medium, a development apparatus that develops the electrostatic image to form a toner image, and a heat transfer unit that transfers the toner image onto the recording sheet by Ion-Deposition imaging techniques (or by electrophotographic techniques). The toner remaining on the recording medium is removed by applying a direct-current to the development apparatus.
