ABSTRACT:
An one-component developing device includes an electrically conductive member which is located in a region extending from a position downstream, with respect to a moving direction of a surface of a toner carrying member, to a developing region, and is in contact with the surface of the toner carrying member. A surface of the electrically conductive member contacting the developing sleeve is formed of material, of which charge polarity is shifted to the same polarity side as a regular charge polarity of the toner in view of charge series, and which contains highly conductive material dispersed therein.
