    摘要： A developing device for developing a latent image formed on an image carrier of the present invention is generally made up of a developing section and a developer storing section. The developing section includes a developer carrier for conveying a one-component type developer deposited thereon, a feeding member for feeding the developer to the developer carrier, and a conveying member for conveying the developer toward the feeding member while agitating it. The developer storing section replenishes a developer stored therein to the developing section in a direction including at least a horizontal direction component. The developing section and developer storing section are formed with a plurality of openings in the lengthwise direction such that the replenishment of developer from the developer storing section to the developing section and the return of the developer from the latter to the former are executed via the openings.

    摘要： An image forming apparatus of the present invention includes a bias power supply for applying a bias VB to a developer carrier on which a developer is deposited. A charge potential deposited on an image carrier, which faces the developer carrier for forming a latent image thereon, is 400 V or below in absolute value. Assume that the potential of the image carrier is lowered to VL after exposure, that a development potential is |VB−VL|, that the maximum set value of the development potential for development is |VB−VL|max, and that the development potential varies in a range satisfying relations: |VB−VL|≦|VB−VL|max+|VB−VL|max×0.2 |VB−VL|≧|VB−VL|max−|VB−VL|max×0.2 |VB−VL|max≦300 V Then image density varies by a width of 10% of image density corresponding to the maximum set value of the development potential or less.
