A developing apparatus includes a developer container for containing a developer containing toner and carrier particles having a volume resistivity of 10<6>-10<10 >Omegacm; a developer carrying member for carrying the developer contained in the developer container; a voltage applying means for applying a developing bias voltage having a DC component and an AC component to the developer carrying member when an electrostatic image formed on an image hearing member including a surface layer having a volume resistivity of 10<9>-10<14 >Omegacm is developed by contacting the developer carried on the developer carrying member to the electrostatic image, wherein a volume resistivity of the developer carrying member is 1x10<-1>-1x10<2 >Omegacm.
