An electrophotographic copier includes a transfer/charge section, a developer/cleaner section, and a photoreceptor having a surface with first and second image areas. Copies are produced by moving the photoreceptor a half revolution so that the first image area passes through the transfer/charge section in which a uniform charge is applied to the first image area. The charged first image area is exposed to a light image producing an electrostatic image on a surface of the photoreceptor. Toner is applied to the exposed first image area as it passes through the developer/cleaner section. The toned image is transferred to paper by moving the first image area through the transfer/charge section, after which the toner is fused onto the paper. When an another copy is to be made, the second image area passes through the transfer/charge section to apply a uniform charge to that image area while the developer/cleaner section removes residual toner from the first image area. Then the second image area is used to produce the next copy. Otherwise the transfer/charge section is not activated and only the residual toner is removed from the first image area before the copying process ends.
