ABSTRACT:
A device including a developing roller having a magnet roller for transporting developer, and developing an electrostatic latent image, a regulating member regulating transportation amount of the developer transported to the electrostatic latent image with the development roller, and a reflux plate refluxing excess developer regulated by the regulating member away from the regulating member is constructed to comprise a rubbing member arranged to face the developing roller, at a second gap larger than a first gap defined by the developing roller and the regulating member, and rubbing developer transported to the first gap. The rubbing member carries out preliminary electrification on developer and then the regulating member carries out main electrification on the preliminarily electrified developer.
