摘要：
A developing apparatus includes an image bearing member for bearing an electrostatic image, a developer carrying member, opposed to the image bearing member to form a developing zone therebetween, for carrying a developer to the developing zone to develop an electrostatic latent image on the image bearing member, and oscillating bias means for applying an oscillating bias to the developer carrying member, wherein the oscillating bias includes a constant-current-controlled AC component and a constant-voltage-controlled DC component.
