ABSTRACT:
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.
