ABSTRACT:
An electrophotography developing apparatus of non-contacting type using a nonmagnetic one-component toner is provided. The developing apparatus adopts a soft roller as a developing roller and a developing gap of 50-200 .mu.m is formed between a developing drum and developing roller. A desirable image can be provided by adopting the soft roller as the developing roller and properly setting the developing gap between the developing roller and the developing drum. Generally, the electrophotography developing apparatus is used in the apparatus for printing and communicating, such as a duplicator, a printer and a facsimile.
