摘要： An electrophotographic copying method is carried out by the use of a developing material consisting of a magnetic toner of a volume resistivity within the range of 10.sup.10 to 10.sup.14 .OMEGA..multidot.cm and a non-magnetic and electrically insulating toner. During the development of an electrostatic latent image on a photoconductive support member into a toner image by means of a magnetic brush developing process, particles of both of the magnetic and non-magnetic toners are caused to deposit on an image area of the electrostatic latent image and particles of only the magnetic toner are caused to deposit on a non-image area of the electrostatic latent image. The toner image so developed is subsequently transferred from the photoconductive support member to a sheet of final support material and then fixed.
