摘要： A developing unit for use in image forming apparatus includes a unit housing divided in three chambers, i.e. a toner applying chamber facing a photoreceptor and first and second toner replenishing chambers, by respective partition walls each having an opening as a passage for toner. The first and second chambers have rotation frames, respectively. Each frame has a radially extending arm to the end of which a toner transporting sheet is connected. Each sheet is provided with a friction film. When each frame rotates, the sheet with the friction film is pulled by the frame for its rotation under the toner so as to be deformed in the form of a circular arc. The toner is transported forwardly by the friction force of the friction film. When the amount of toner is reduced in each chamber, each sheet may resiliently restore to its original shape to contact the inner surface of the corresponding chamber so that a small amount of toner on the bottom of each chamber can be carried forwardly.

摘要： An image forming apparatus includes a photoconductor, a developing electrode, at least a magnet disposed in the developing electrode, and a developer. The developing electrode is reciprocally movable against a rotation axis of the photoconductor. Thus, a setting angle of a magnetic pole of the magnet is not varied, even when the developing electrode is moved for cancelling decentering and deflection of the photoconductor and the developing electrode.

摘要： Disclosed is an electrophotographic apparatus capable of producing a high-quality image free from image defects such as fine line dropouts. A photoconductor drum is used that has a magnet mounted therein in immovable fashion. After an electrostatic latent image is formed, the image is brought into contact with magnetic developer in a developer reservoir, causing the developer to be attracted to the photoconductor surface by magnetic force. When the photoconductor drum is rotated past an electrode roller to which an AC voltage is applied, toner is left only in image areas and the latent image is developed into a visible image. A sheet-like sealing member contacting the photoconductor is disposed on the upstream side of the developer reservoir in the rotating direction of the photoconductor drum. A conductive layer is provided on the surface of the sealing member opposite the surface thereof contacting the photoconductor.

摘要： A toner layer forming device is used for a developing device of an electrophotographic device, in which a toner holding member rotates in a predetermined direction while holding on its surface a nonmagnetic toner containing a detachant. A rotary toner layer control member whose surface rotates in the reverse direction to the surface of the toner holding member while contacting the surface with the surface of the toner holding member is provided in order to control the nonmagnetic toner layer. A toner removing member partially contacts with the surface of the rotary toner layer control member in order to scrape off the nonmagnetic toner held on the rotary toner layer control member, so that the toner on the rotary toner layer control member can be removed smoothly and a stable toner layer can be formed.

摘要： An electrophotographic apparatus includes a photoconductor drum, also known as an electrostatic latent image holding member, with a magnet placed therein. An electrostatic latent image is formed on the magnetic drum. Then, the drum is brought into contact with a magnetic developer, or toner, in a developer reservoir to have the magnetic developer attached to the photoconductor drum surface by a magnetic force. A removing roller, having an AC voltage applied thereto, is passed in close vicinity of the magnetic drum with the resultant development of images because toner remains at image areas only. In the electrophotographic apparatus, the photoconductor drum, the removing roller or both include two magnetic poles. A device for increasing friction force of the surface of the photoconductor drum, of the removing roller or both may also be provided.

摘要： An image forming device in which the toner density of a two-component developing device can be stably controlled in printing a one-page image and the frequency of interruption of even printing a series of pages can be decreased as less as possible. The number of pixels of the image relevant to the development counted during the printing and the toner consumption is estimated from other image information, and the amount of toner corresponding to the consumption is supplemented. In this supplement, the count is acquired at an intermediate time of the one-page printing, the toner consumption is estimated, and the toner is supplemented during the printing after the intermediate time. Thereby, toner supplement can be performed ahead of its schedule, and a variation of the toner density can be prevented correspondingly.
