摘要： An intermediate transfer belt and a photosensitive member form a transfer nip. An electrode is arranged close to an inner surface of the intermediate transfer belt in a portion on an upstream side of a direction of endless movement of the intermediate transfer belt with respect to a downstream-side exit of the transfer nip and on a downstream side of the direction of endless movement with respect to a position at which a transfer roller charges the intermediate transfer belt. A voltage of same polarity as the polarity of a toner is applied to the electrode, so that there is no movement of an electric charge between the electrode and the intermediate transfer belt.

摘要： A developing device for an image forming apparatus includes a developing roller for conveying toner deposited thereon to a developing region where it faces a photoconductive element. A magnet brush roller conveys a two-ingredient type developer, which consists of toner and magnetic particles, deposited thereto to a toner supplying region where it faces the developing roller. In the toner supplying region, only the toner is supplied from the magnet brush roller to the developing roller. The distribution of the number of toner particles for an amount of charge differs from the developing roller to the magnet brush roller.

摘要： A developing unit of the present invention includes a developing roller facing a photoconductive element and formed with a magnetic layer on its circumference. The magnetic layer has a plurality of magnetic poles of opposite polarities alternating with each other and each extending in the axial direction of the developing roller. A developer consisting of magnetic particles an toner are deposited on the developing roller by the magnetic poles and conveyed by the roller to the photoconductive element carrying a latent image thereon, thereby developing the latent image. An agitator for agitating the magnetic particles and toner is positioned relative to the developing roller such that a blade thereof has an agitation range overlapping with the magnetic force range of the magnet layer. With this configuration, it is possible to insure high quality images free from background contamination and toner scattering while extending the service life of the developing unit.
摘要翻译：本发明的显影单元包括面向感光元件的显影辊，并在其圆周上形成有磁性层。磁性层具有彼此交替的多个相反极性的磁极，并且各自在显影辊的轴向上延伸。由磁性颗粒构成的显影剂由调色剂通过磁极沉积在显影辊上，并被辊传送到在其上携带潜像的光电导元件，从而显影潜像。用于搅拌磁性颗粒和调色剂的搅拌器相对于显影辊定位，使得其叶片具有与磁体层的磁力范围重叠的搅拌范围。通过这种配置，可以确保高质量的图像免于背景污染和调色剂散射，同时延长显影单元的使用寿命。

摘要： An image density control method for an image forming apparatus determines the density of a toner image formed on a photoconductive element by a reflection type photosensor and, if the density is low, supplies a toner to a developing unit. A latent image representative of a reference pattern is electrostatically formed on the photoconductive element and then developed by a toner supplied from the developing unit. The supply of a toner to the developing unit is controlled on the basis of the outputs of the sensor associated with the area of the photoconductive element where the pattern image exists and a non-image area. A particular bias voltage is applied to the developing unit for each of the image area and non-image area.

摘要： An exposing apparatus for use in a color copier in which reflection light from an original image mounted on an original mounting plate thereof and illuminated with white light is passed through three color separation filters which are inserted, in sequence, into an optical path of a common focussing system of said copier, and color-separated images obtained from said filters are focussed in sequence on a common image plane. Transparent flat plates having thicknesses suitable to correct optical path lengths for the respective color-separated lights such that effective value of focussing optical path lengths of a focussing element of the focussing system for the respective color-separated lights become equal to a distance of the focussing system between a plane of the original and the image plane are inserted into the focussing optical path in sequence in synchronism with the sequential insertion of the color separating filters into the optical path.

摘要： A transfer apparatus is provided of the type in which a toner image formed on a photosensitive member is transferred onto a transfer or copy sheet. The apparatus is used in a copying machine of a so-called delivery type in which the sheet is conveyed using a sheet gripper. During the transfer of a toner image, the appartus applies a corona discharge to the rear side of the sheet which is of the opposite polarity from that of the toner image. The apparatus comprises a diaphragm member for restricting an opening of a transfer charger and disposed between the transfer charger and the photosensitive member, the diaphragm member being movable away from the photosensitive member as the sheet gripper passes between the transfer charger and the photosensitive member.
