Abstract
A developer mixture used in an electrophotographic printing machine to develop an electrostatic latent image recorded on the photoconductive member includes weakly magnetically attractable toner particles and strongly magnetically attractable carrier granules adhering triboelectrically to one another. The toner particles and carrier granules are substantially the same size. During development, the toner particles are deposited on the latent image forming a toner powder image. Subsequently, the toner powder image is transferred to a copy sheet and permanently fixed thereto.
