Developing unit for electrophotographic apparatus

摘要

A developing unit for an electrophotographic apparatus with a photosensitive drum is described. A developing roll 18 develops a latent image formed on the surface of the photosensitive drum with toner 24. A toner supply roll 10 includes a cross-shaped member mounted on a shaft 14, each branch 12 of the cross-shaped member comprising a blade for supplying the toner 24 to the developing roll. Each such blade 12 is tapered toward its outward end so as to enhance the supply of toner to the developing roll 18. <IMAGE>
