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.

摘要： One or more rows of focussing optical fibers are disposed between an original document carrier and a photoconductive member. An illumination lamp illuminates an original document on the carrier and the fibers focus an image of a linear portion of the document onto the photoconductive member. Relative movement between the document carrier, fibers and photoconductive member perpendicular to the row or rows of fibers is produced to scan the document. An aperture assembly is provided between the fibers and the photoconductive member difining an aperture wide enough that unevenness of the intensity of the image on the photoconductive member due to the individual fibers is eliminated. The intensity of the light image is controlled by utilization of a variable transformer or triac provided to the illumination lamp.

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： 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.
