摘要： A method of forming a powder image on a recording medium and an apparatus therefor are disclosed. The apparatus includes a toner carrier for carrying powdery toner in a layer or layers thereon, a counter electrode, and a flight control member having independent or continuous extremely small holes and a plurality of control electrodes for controlling the passage of toner through the holes. A voltage is applied to the control electrodes in accordance with an image signal in order to cause the toner to fly from the toner carrier toward the counter electrode via the holes. The toner deposits on the recording medium intervening between the flight control member and the counter electrode, forming an image on the recording medium. The method and apparatus are capable of increasing a recording speed, recording an image even on a paper in a humid environment or on a conductor, simplifying circuitry for driving control electrodes included in the flight control member, promoting the effective use of drivers during image formation, causing only a part of toner for forming an image to fly, and reducing the cost.

摘要： A charging apparatus for use in an image forming apparatus includes a charge roller configured to adjoin to a photoconductive member to provide a charge to a surface of the photoconductive member. The charge roller includes a plurality of roller layers. One of the plurality of roller layers has a resistance ratio with which a roller surface potential is raised by a charge movement. In this case, the resistance ratio has a value such that a time period in which a charge moves within the one of the plurality of roller layers is sufficiently smaller than a time period in which an arbitrary point of the surface of the charge roller moves across a discharge region formed between the charge roller and the photoconductive member.

摘要： An ink jet head used for pulsed droplet ink jet printer uses a grooved piezo-electric element. The piezo-electric element includes a plurality of grooves, diaphrams and actuators. The actuator and two grooves at both sides of the actuator, filled with stuffing material, covers a corresponding one of passages. Therefore, even if the stuffing material moves when the actuator is energized, an interference problem does not occur. Consequently, the flexure force of each actuator can transmit to the corresponding passage to jet ink in the passage via a nozzle.

摘要： A toner for electrophotography satisfies Ft/Dt≦3.0 [nN/μm], where Ft is an inter-toner non-electrostatic adhesion force after a compressive stress within 0.7×10−2 [N m2] to 1.5×10−2 [N/m2] is applied, and Dt is a diameter of a toner particle. The inter-toner non-electrostatic adhesion force is obtained by filling a two-dividable cell for an Agrobot AGR manufactured by Hosokawa Micron Corporation having a diameter of 15 mm, measuring a tensile rupture stress required for dividing the cell after a compressive stress is applied, and substituting the tensile rupture stress into Rumpf's equation.
