ABSTRACT:
An aspect of the invention provides a developing device including: a developer container that contains developer and is formed with an opening; a developing roller that is rotatably supported by the developer container at a predetermined position and includes a roller shaft and an elastic roller configured to carry the developer; leakage preventing members that prevent leakage of the developer at longitudinal end portions of the elastic roller and each of which is respectively disposed at portions, where the longitudinal end portions oppose the developer container, to extend in an extending direction along a circumferential surface of the elastic roller at a longitudinal end portion thereof; and a guide that is provided on the developer container and slidably guides the developing roller toward the predetermined position along a sliding direction that is defined along the extending direction to allow the developing roller to be attached to the developer container.
