シ現像装置。 The fur brush developing roller is provided with a fur brush developing roller that supplies toner particles onto the photoreceptor, and a replenishment roller that contacts the surface of the fur brush developing roller and replenishes the charged toner to the fur brush developing roller. In a fur brush developing device to which a developing bias voltage having a potential higher than that of the fur brush developing roller is applied, a collection roller is disposed at a position in contact with the surface of the fur brush developing roller on the upstream side in the rotational direction of the fur brush developing roller with respect to the replenishing roller. , a fur brush developing device characterized by applying a recovery bias voltage larger than the developing bias voltage to the recovery roller and removing means for removing toner adsorbed to the recovery roller on a toner replenishing side. .
