摘要： A particulate magnetic toner for use in a process for developing latent electrostatic images to toner images with a magnetic brush consists predominantly of a magnetic material and a resin of insulating properties. Each toner particle has a portion containing the magnetic material, said material extending through the particle and at least exposed on opposing surfaces of each toner particle to oppose the magnetic materials of other toner particles.

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.
