Abstract
A development device includes: a developer carrier configured to develop an electrostatic latent image with a developer while rotating, the electrostatic latent image being carried on a surface of a rotating electrostatic latent image carrier; and first and second developer supply members configured to, while rotating, supply the developer carrier with the developer contained in a developer container. The first developer supply member and the second developer supply member are disposed at positions opposed to the developer carrier, and in contact with the developer carrier. The first developer supply member is disposed downstream of the second developer supply member in a rotational direction of the developer carrier. A first contact amount at which the first developer supply member is in contact with the developer carrier is set smaller than a second contact amount at which the second developer supply member is in contact with the developer carrier.
