Patent ID: 8010023

Claim:
A developing device, comprising: a developer carrier that is rotatable and disposed facing an image carrier; a conductive developer supply and recovery member rotatably arranged so as to abut the developer carrier with a contact pressure P between the developer carrier and the conductive developer supply and recovery member satisfying the relationship 0 (kPa)<P<5.0 (kPa), the conductive developer supply and recovery member being charged with a DC bias to move regularly-charged developer on the developer carrier in a direction towards the conductive developer supply and recovery member; and a conductive charging member in contact with the developer carrier, at a position further downstream in the rotation direction of the developer carrier than a position at which the developer carrier and the image carrier oppose each other, and further upstream than the abutting position of the developer carrier and the conductive developer supply and recovery member, the conductive charging member being charged with a DC bias in a direction in which the regularly-charged developer on the developer carrier moves towards the developer carrier, to charge developer that remains on the developer carrier without having been supplied for developing after returning from the position at which the developer carrier and the image carrier oppose each other as the regularly-charged developer, a rotation direction of the conductive developer supply and recovery member being opposite to a rotation direction of the developer carrier at a position where the developer carrier and the conductive developer supply and recovery member abut each other.
