ABSTRACT:
A device for developing a latent image on an image bearing member includes a developing roller, rotatably mounted facing the image bearing member, for transferring a developing agent to the image bearing member, and a supply roller, rotatably mounted adjacent to the developing roller, for supplying the developing agent to the developing roller at a supplying portion. The developing agent is stored in the storing member and is provided to the supply roller upstream of the supplying portion with respect to a rotating direction of the supply roller. A disordering member, mounted downstream of the supplying portion with respect to the rotating direction of the supply roller, disorders the developing agent on the surface of the supply roller to prevent the developing agent from causing hardening of the supply roller.
