摘要：

A developing device (21) including: a first developer carrying member (23) for carrying a developer to develop a latent image formed on an image bearing member (1); a first regulating member (29), disposed on one end of a longitudinal direction of the image bearing member, for regulating a gap between the image bearing member and the first developer carrying member; a second developer carrying member (24) for carrying a developer to develop the same latent image formed on the image bearing member; and a second regulating member (30), disposed on the one end of the longitudinal direction of the image bearing member, for regulating a gap between the image bearing member and the second developer carrying member, wherein the first and second regulating members are disposed without being superposed upon each other in the longitudinal direction.
