ABSTRACT:
Three primary color toner images are transferred successively onto a copy sheet from three photoconductive drums. The copy sheet is successively moved into engagement with the drums in register with the toner images by an endless belt. Various transfer charging means are provided to electrostatically adhere the copy sheet to the belt and counteract an adverse accumulation of charge on the copy sheet caused by accumulation of toner substance thereon during the three successive transfer operations.
