Abstract

A non-magnetic one-constituent developing agent is an electro-photographic developing agent that provides high quality images without fogging, scattering of toners and ineffective development by maintaining stable charges and a uniform distribution of toners over an extended lifetime in a developing apparatus of an electro-photographic image processing device. In addition, the developing agent has deodorizing, anti-bacterial and sterilizing functions.
