    摘要: A dry developer for an electrophotographic process, said dry developer being composed of a toner and a dispersion type carrier composed of a resin and a magnetic powder, wherein polyethylene having a molecular weight of not larger than 10,000, a density of at least 0.95, and an average volume diameter of not larger than 15 .mu.m is externally added to the toner or directly mixed with the developer. The dry developer shows good fluidity and cleaning property, is excellent in environmental stability and durability, and can prevent the occurrence of the toner film phenomenon on a photoreceptor or carrier surfaces.
