Abstract
New liquid developers for electrophotography comprise (a) a coloring agent, (b) a charge control agent and (c) one or more of a polyethylene, a polypropylene, an ethylene copolymer and a propylene copolymer, with or without (d) a hydrocarbon resin soluble in a hydrocarbon solvent and containing a 1,3-pentadiene moiety, in an electro-insulating liquid. These developers have an excellent etching resistance and a high dispersion stability.
