Patent ID: 8175503

Claim:
A developing device, comprising: a developing roller arranged to face a photoconductor for forming an electrostatic latent image and adapted to supply a toner to the photoconductor; an agitating member having at least one screw member for agitating a developer; a supply roller that holds the developer agitated by the agitating member, and supplies the toner to an area facing the developing roller; a restricting member for blocking the developer supplied onto the supply roller and restricting the amount of the developer conveyed by the supply roller; and an intermediate roller which is provided in such a manner that a rotational center of said intermediate roller is higher than said agitating member and below a rotational center of the supply roller, and in a top view, a rotational center of said at least one screw member is between the rotational center of the supply roller and the rotational center of the intermediate roller, said intermediate roller is provided to face the developer being blocked by the restricting member, and includes a first magnetic pole provided to face the developer blocked by the restricting member, said first magnetic pole being provided for attracting the developer that is restricted by the restricting member.
