Multi-color method of toner transfer using non-marking toner and high pigment marking toner

Abstract

This invention provides a method and apparatus which forms a desired toner image on a receiver by: forming at least one electrostatic image on at least one imaging member; toning at least one said electrostatic image with marking toner particles of at least one color; transferring said marking toner particles from at least one said imaging member to the surface of an intermediate transfer member in the presence of an electric field which urges said marking toner particles toward said intermediate transfer member; and transferring said marking toner particles from said intermediate transfer member to a receiver in the presence of an electric field which urges said marking toner particles toward said receiver; wherein, when transferring said marking toner particles to said intermediate transfer member from at least one said imaging member, said surface of said intermediate transfer member contacts non-marking toner particles in areas which receive marking toner, and wherein said marking toner particles have a volume weighted diameter of 2 to 8 .mu.m and comprise pigment at a concentration of from 10 to 50% by weight of the total toner composition.
