Patent ID: 8224218

Claim:
A developing device, comprising: a photosensitive member having a surface on which a visible image is formed; and a developing member to feed a developer to the photosensitive member wherein the photosensitive member includes a developing region, to which the developer is transmitted by the developing member, and a transfer region, from which the developer of the photosensitive member is transmitted to a recording medium, and a redistributing unit is disposed between the developing region and the transfer region, to redistribute the developer present on the photosensitive member, wherein an alternating-current (AC) power is applied to the redistributing unit to cause the developer to oscillate between the redistributing unit and the photosensitive member and a direct-current (DC) power is further applied to the redistributing unit to cause the developer to adsorb to the photosensitive member to thereby redistribute the developer present on the photosensitive member.
