Patent ID: 7221892

Claim:
A developing device, comprising: a developer-carrying member that conveys a charged nonmagnetic single-component developer to a surface of an image-carrying member; a supplying member that supplies a developer to the developer-carrying member; a removing member that removes a charged nonmagnetic single-component developer remaining on a peripheral surface of the developer-carrying member that was not supplied to the image-carrying member; and a removing device that removes the charged nonmagnetic single-component developer from the removing member, the removing device being arranged to contact the removing member, wherein: the developer-carrying member rotates in a rotational direction such that the peripheral surface of the developer-carrying member opposing the supplying member moves vertically downward; the removing member is positioned vertically above the supplying member and upstream of the supplying member in the rotational direction of the developer-carrying member; the removing member rotates such that a peripheral surface of the removing member opposing the developer-carrying member moves in the same direction as the peripheral surface of the developer-carrying member opposing the removing member at a contact position with the peripheral surface of the developer-carrying member; and a bias is applied to the removing member and the developer-carrying member so as to attract the charged nonmagnetic single-component developer from the peripheral surface of the developer-carrying member onto the removing member, wherein the removing member is formed of a conductive material.
