Abstract
An improved apparatus is disclosed for developing images on an electrophotographic copy sheet, characterized by the provision of a distribution roller having a soft porous peripheral surface for evenly spreading the toner dispersion on the electrophotographic copy sheet. The distribution roller is arranged between pairs of in-feed and squeeze roller means arranged in the developing chamber for transporting the electrophotographic sheet therethrough. Improved spray tube means are also provided for spraying the toner dispersion uniformly upon the peripheral surface of the upper in-feed roller.
