摘要： An image forming apparatus of the present invention includes a developing device of the type causing a developer to form a magnet brush on the surface of a developer carrier having a magnet roller in a developing region or nip for development. The magnet brush contacts and thereby develops a latent image formed on an image carrier. The magnet roller has a main magnetic pole for development wherein the flux density in the tangential direction has a maximum variation ratio of 40 T/m or above in absolute value. The apparatus of the present invention increases image density and faithfully reproduces even low-contrast images with a low-cost configuration. Further, the apparatus reduces image defects, including granularity and the omission of the trailing edge of an image, even if the range over which the magnet brush and image carrier contact is reduced.

摘要： The development is performed under a condition that |Q2|−|Q1|/|Q1≦±0.45. Here, Q1 denotes an average amount of charge on toner held on a development roller and carried toward a development region immediately before development. Q2 denotes an average amount of charge on toner immediately before development held and carried toward the development region in the state immediately after development of an electrostatic latent image on a development drum. This is effective to allow the amount of charge q/m on toner held on the development roller to have a variation rate of 45% or below and an afterimage rate R within 2%.
摘要翻译：在| Q2 | - | Q1 | / | Q1 <=±0.45的条件下进行显影。这里，Q1表示保持在显影辊上的调色剂上的平均充电量，并且紧靠显影前的显影区域携带。 Q2表示紧接在显影鼓上的静电潜像显影后立即显影状态下保持并承载于显影区域的调色剂上的平均电荷量。这有助于使显影辊上保持的调色剂上的电荷量q / m具有45％以下的变化率和2％以内的残像率R。
