Disclosed is an imaging system wherein there is provided an imaging suspension of photoelectrophoretic imaging particles in an insulating carrier liquid. There is added to this imaging suspension comprising light sensitive particles in a carrier liquid, a substantially colorless or transparent particle thereby improving the quality and permanency of the resulting image. This imaging suspension is placed in an electroded system, exposed selectively to an electromagnetic radiation source while applying voltage across the imaging suspension. Particle migration takes place within the system, resulting in a visible image at one or both of the electrodes.
