摘要： A developing device includes 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, and an image forming apparatus having the developing device. 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. A redistributing unit is disposed between the developing region and the transfer region, to redistribute the developer present on the photosensitive member. When developing a solid image and a halftone image in sequence is desired, even if a portion of the developer for use in development of the halftone image is prematurely transmitted to the photosensitive member, the redistributing unit can redistribute the transmitted developer so as to use the transmitted developer to develop the halftone image, resulting in a reduction in likelihood of image defects.
