    摘要： A development device can include a developer containing part containing developer, a carrier to carry developer that is supplied from the developer containing part to a development range, a partition dividing the developer containing part into a supply part and a circulation part beneath the supply part to collect developer from the carrier, a first transport member in the supply part of the developer containing part to supply developer from the supply part to the carrier, and a second transport member in the circulation part to transport developer in the circulation part in an axial direction of the carrier. The device can also include a removable seal member, which seals a supplied-developer and/or a collected-developer communicating area.

    摘要： An electrophotographic image forming apparatus of the present invention frees images from various defects including the thinning of horizontal lines, the omission of the trailing edge of an image, background contamination, granularity particular to a halftone image, carrier scattering, and image noise. Further, the apparatus of the present invention solves problems ascribable to patches used to sense image density. Moreover, the apparatus of the present invention faithfully reproduces tonality and has a high developing ability.

    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.

    摘要： In an image forming apparatus, the rise and fall of a short magnet brush are realized and allow a nip for development to be reduced. This, coupled with the fact that the short magnet brush uniformly rises and falls in the axial direction of a developing sleeve, frees the trailing edge of an image from local omission or jaggedness while reducing defective images including a thinned dot image.
