ABSTRACT:
In an electrophotographic image formation method including the steps of uniformly charging a photoconductor, exposing the charged photoconductor to a digitally-processed light image to form a latent electrostatic image, and developing the latent electrostatic image by reverse development with a dry type two-component developer composed of a carrier and a toner to a toner image, transferring the toner image to a transfer sheet, and cleaning the photoconductor to remove the remaining developer from the surface of the photoconductor, a carrier removing device including a magnet with a magentic flux density of 400 to 2000 Gauss is provided between the development step and the cleaning step.
