Abstract
A magnetic developing process for use in electrophotographic or electrostatic recording techniques employs a magnetic brush formed by a developer which comprises a powder mixture of a low resistance toner and a high resistance toner, at least one of which comprises a magnetic toner. Both toners are triboelectrically charged, and the magnetic toner serves as a carrier, so that both toners are attracted to an electrostatic image to provide a developing thereof.
