ABSTRACT:
A dry-type developing device is capable of converting electrostatic latent image formed on the surface of latent image carrying member to visible image by use of developer powder, and the developing device comprises a latent image carrying member for carrying electrostatic latent image formed thereon at the respective different positions, a first developer carrying member for holding thereon two components type developer having non-magnetic toner and magnetic carrier, a second developer carrying member disposed so as to adjacently oppose the first developer carrying member and the latent image carrying member, a control device for regulating the amount of developer on the first developer carrying member, a first electric field forming device for forming a first direct-current electric field between the first and second developer carrying members, and a second electric field forming device for forming a second direct-current electric field between the latent image carrying member and the second developer carrying member.
