摘要： A developing device capable of obviating the cohesion of toner and reducing the amount of dead toner is disclosed. The device has a developing unit accommodating a first and a second screw therein. The first and second screws extend from the toner hopper to the other longitudinal end of the developing unit in parallel to a developing roller and a supply roller. The first screw feeds toner from a toner hopper to a developing section. The second screw collects toner not contributed to development from the developing section and returns it to the first screw for recirculation. In this configuration, the collected toner and dead toner aggregating in the lower portion of the developing unit are forcibly moved to the developing section. The direction in which the screw portion of the second screw is inclined may be partly reversed to form a reverse transfer portion. Alternatively, a part of a casing adjoining the hopper may be implemented as a slant. The reverse transfer portion or the slant recirculates the toner more forcibly.

摘要： A developing device for an image forming apparatus and using a one component type developer. The developer is transferred from a developer supply member to a developer carrier which are so rotated as to move in the same direction at a position where they contact each other. This prevents the developer from a toner storing section from directly reaching part of the developer carrier having moved away from the contact position despite the movement of the developer supply member. Conductive portions connected to ground and dielectric portions each having a small area are distributed regularly or irregularly on the surface of the developer carrier. Such a surface of the developer carrier is charged by friction by the developer supply member with the result that a great number of microfields are formed in the vicinity of the developer carrier. The microfields allow only the developer sufficiently charged by friction at the contact position to form multiple layers on the surface of the developer carrier. Consequently, the toner with a desired amount of charge and containing a minimum of uncharged toner can form multiple layers on the developer carrier and is transferred to an image carrier.

First, the optical mechanism is positioned in a reference position. Then, the optical mechanism is displaced by successive intervals while photographing the images successively on the photosensitive medium at respective areas thereon with the optical mechanism.

摘要： A ferroelectric memory structure is described for the 1T1C arrangement in a ferroelectric capacitor cell array for FeRAM memory device applications. The device structure provides an accurate reference voltage and a simple sensing scheme for the sense amplifier used for reading the state of a target memory cell of the FeRAM array. A reference circuit generates a reference voltage which is a function of a charge shared between a plurality of FeRAM dummy cells. Each dummy cell of the plurality of FeRAM dummy cells is selectively coupleable to a plurality of bitlines. A shorting transistor in the reference circuit couples two bitlines or two bitline-bars neighboring the selected target memory cell. One dummy cell is coupled to a select one of the two shorted bitlines or bitline-bars, and another dummy cell is coupled to a another of the two shorted bitlines or bitline-bars, wherein at least one dummy cell is biased to a “0” state, and at least one other dummy cell is biased to a “1” state. As charge sharing takes place between the bias states of the dummy cells and the shorted bitlines, an averaged reference voltage is produced which is substantially centered between the “0” or “1” states. A sense amplifier receives a sense signal from the target memory cell on an associated bitline, and the averaged reference voltage is received on another bitline input of the sense amplifier. Thus, a new ferroelectric memory structure provides a centered reference voltage and a simple sensing scheme for the accurate sensing of the logic state of an FeRAM 1T1C cell for a read operation.
