ABSTRACT:
A developer is composed of colored insulating particles for developing an electrostatic image wherein at least the external surface of each particle comprises two different areas of which one area constitutes a major portion of said external surface and comprises an element which defines the polarity of the triboelectric charge of said particle to a determined polarity while the other area comprises an element capable of being easily separated from said particle, transferred to a surface of a developing device and charged to a polarity opposite to that of said particle.
