摘要： An electromechanical actuator includes an electric motor and a control and drive circuit mounted integrally with the electric motor. The control and drive circuit includes a serial-to-parallel converter for converting a control signal in the form of serial data into parallel data, and a device responsive to the control signal in the form of parallel data for producing a drive current or voltage for the electric motor. A system for accessing or controlling a plurality of such actuators by commands from a main controller can include a control and drive circuit which is integral with the motor itself.

摘要： An image forming apparatus includes a latent image bearer, a developing device, a toner container, a toner feed connector, a processor, and a notifier. The developing device develops, with toner, a latent image on the latent image bearer. The toner container contains the toner. The toner container is detachably attachable to the image forming apparatus. The toner feed connector guides the toner of the toner container to the developing device. The information detector detects identification information including toner type information and maintenance contract information stored in the toner container. The processor determines whether the toner type information of the toner container coincides before and after replacement and whether the maintenance contract information of the toner container is matched with maintenance contract information of the image forming apparatus. The notifier indicates a determination made by the processor.

摘要： A development device includes a development roller, a developer storage, a first rotating member, a second rotating member, and a rotation speed adjuster. The development roller carries a developer containing non-magnetic toner and magnetic carrier. The developer storage stores the developer. The first rotating member is provided in the developer storage at a position near the development roller. The second rotating member is provided in the developer storage at a position farther from the development roller than the first rotating member is. The first rotating member and the second rotating member agitate and convey the developer stored in the developer storage to supply the agitated developer to the development roller. The rotation speed adjuster adjusts a rotation speed of the second rotating member depending on an amount of new toner supplied to the developer storage.

摘要： A developing device includes a developing roller that carries a two-component developer from a developer container to an image carrier, a first screw carrying a developer, and a second screw carrying the developer in a direction opposite to a direction in which the first screw carries the developer. The first screw and the second screw circularly convey the two-component developer while stirring the two-component developer to supply the two-component developer to the developing roller. A rotation speed of the second screw and a rotation speed of the developing roller can be drive-controlled independently, and a ratio of a rotation speed between the second screw and the developing roller is variable.

摘要： An electrophotographic image forming apparatus capable of reliably forming an image with density gradation, one which does not have a low-quality appearance. The estimated average halftone granularity of the toner image after developing but before electrostatic transfer was set at 0.25 or less. The average halftone granularity was found by measuring the granularity of a toner image at locations of different average brightness by means of newly proposed formula, and averaging the measured values for which the average brightness is 40 to 80. The estimated average halftone granularity was obtained by estimating the average halftone granularity of the toner image on a photoreceptor by means of a newly proposed method.
