A phase change developer can reversibly change from a solid state to a liquid state at its melting/crystallization temperature. This phase change developer is solid in storage and before imaging development. During image development, it melts at a temperature above its melting point to form a liquid developer which then undergoes the process of liquid electrophotographic development to produce toned images. These unique characteristics of the phase change developer were achieved using a binder which contains a polymerizable crystallizable component (PCC). The resulting images exhibited high gloss, high resolution, good transparency, and superior blocking and erasure resistances.
