A sheet of paper, plastic or the like on which an image has been formed using a toner that is photochemically decolorizable by absorption of near infrared rays is illuminated with near infrared rays under the state wherein the image is heated to a temperature equal to or higher than the glass-transition temperature of a binding resin of the toner. The color of the toner can thereby be easily and rapidly eliminated. This enables the reuse of the sheet to be realized easily and at a low cost.

Apparatus for decolorizing toner images and an image forming apparatus

Method and apparatus for decolorization, and image forming apparatus

The transfer and conveying apparatus of the invention transfers a toner image from a photoreceptor onto a recording paper by performing corona discharge at a location opposite to the photoreceptor and adjacent to a portion of a conveying belt which contacts the one of a pair of rollers about which the conveying belt is trained that is closest to the photoreceptor, and conveys the recording paper after transfer of the image by attracting the paper to the belt. This belt is brought into contact with a conductive brush which has AC voltage or DC voltage applied thereto with polarity opposite that applied for transfer of the image to thereby prevent the toner from depositing on the belt. Furthermore, the lower stretched portion of the belt may be wound about the roller through predetermined angular range with the recording paper disposed between the belt and the photoreceptor. The recording paper is thereby resiliently forced against the lower stretched portion of the belt to prevent drooping of the recording paper.

Transfer and conveying apparatus

In an apparatus for conveying dielectric sheets used in copying machines, etc., sheets are held by electrostatic adhesion on the surface of a conveyor when such surface is electrically charged and thus conveyed by the conveyor, wherein a dielectric layer consisting of a dielectric material and electrode parts consisting of a conductive material, which are electrically connected to portions of the dielectric layer and grounded, are provided adjacent to each other on an adhesion surface of the conveyor.
