    摘要： An image forming apparatus of the present invention includes a bias power supply for applying a bias VB to a developer carrier on which a developer is deposited. A charge potential deposited on an image carrier, which faces the developer carrier for forming a latent image thereon, is 400 V or below in absolute value. Assume that the potential of the image carrier is lowered to VL after exposure, that a development potential is |VB−VL|, that the maximum set value of the development potential for development is |VB−VL|max, and that the development potential varies in a range satisfying relations: |VB−VL|≦|VB−VL|max+|VB−VL|max×0.2 |VB−VL|≧|VB−VL|max−|VB−VL|max×0.2 |VB−VL|max≦300 V Then image density varies by a width of 10% of image density corresponding to the maximum set value of the development potential or less.

    摘要： An image forming apparatus includes a latent image bearing member and a developing device for performing a two-level developing operation according to a threshold value of a potential on the latent image bearing member using a one-component developer including toner particles. The developing device has a conveyor to convey the developer to a developing area where the conveyor is spaced from the opposing latent image bearing member by a developing gap. The developing device also has a thin layer forming device to form the developer on the conveyor into a uniform thin layer. A developing bias voltage is applied to the conveyor when the two-level developing operation is performed and developing conditions are established such that an amount of the developer that is moved to and adheres to the latent image bearing member image area is saturated.

    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.

    摘要： To provide a method that can be used to form a high-qualility ferroelectric film by forming good nuclei when using the sputtering method to manufacture a PZT capacitor or other forroelectric capacitors using Ir or other electrode substances in addition to Pt for the electrode. In the method for manufacturing a PZT ferroelectric capacitor CAP, after titanium film 31 is deposited on Ir electrode 6, lead oxide 32 is deposited at a substrate temperature higher than the crystallization temperature of lead titanate using the sputtering method. Lead zirconate titanate 34 is then deposited at a substrate temperature higher than the aforementioned substrate temperature using the sputtering temperature. Afterwards, a heat treatment of the deposited film is performed to produce PZT film 17.
