ABSTRACT:
A developing replenisher material or a replenisher liquid developer to be supplied to a developer tank of an electrostatic copying machine comprises 1000 parts by weight of a carrier liquid composed mainly of aliphatic hydrocarbon and 200 or 1200 parts by weight of toner particles composed mainly of a binder resin and a pigment. The toner concentration of the replenisher liquid developer is high enough to prevent an overflow from the developer tank, allow many copies to be produced by the copying machine, and prevent a solvent shock. The toner particles, when added to the carrier liquid, can immediately and well be dispersed in the carrier liquid.
