Abstract
A development device includes a developer container that contains developer; a rotatable electrostatic latent image carrier that forms an electrostatic latent image thereon, being arranged below the developer container; a rotatable developer carrier that provides the developer to the electrostatic latent image carrier so that the electrostatic latent image is developed with the developer to form a developer image; and rotatable first and second developer supply members that supply the developer to the developer carrier. Wherein the first developer supply member and the second developer supply member are arranged next to each other and facing the developer carrier, and an outer diameter (D12) of a central portion of the first developer supply member in a rotation axis direction is smaller than outer diameters (D11, D13) of two end portions of the first developer supply member.
