摘要： A fixing device of the present invention includes a pressure roller and a peeling roller both of which press a heat roller. The pressure roller is disposed upstream to the peeling roller in a transport direction of a recording paper. An outer diameter of the heat roller, an outer diameter of the pressure roller, and an outer diameter of the peeling roller decrease in this order. With this arrangement, it is possible to realize a fixing device which achieves a reduced size and reduced power requirements, while ensuring a fixing property and a peeling property with respect to a recording medium. Further, with an arrangement in which the pressure roller and the peeling roller which press the heat roller are disposed so that, in a cross section orthogonal to central axes of the heat roller, the pressure roller, and the peeling roller, a first orthogonal line being orthogonal to a first line that connects a center of the heat roller and a center of the pressure roller and passing through a nip portion between both of the rollers, comes into contact with a contact area in a predetermined area on a peripheral surface of the peeling roller, a fixing device of the present invention can transport the recording paper without causing a paper jam when plural pieces of recording paper stacked are transported.

摘要： An image forming apparatus of the present invention includes a toner carrier, a counter electrode, and a control electrode, which have the same potential as a ground potential of the image forming apparatus during a non-operational period while a flight electric field-use operational voltage and control voltages are not applied. During an operational period while the operational voltage and the control voltages are applied, a flight suppressing voltage for suppressing flight of the toner in the control voltages is first applied to the control voltage, and thereafter the operational voltage is applied to the counter electrode. When the application of the operational voltage and the control voltage are suspended, the flight suppressing voltage is first applied as the control voltage, then the application of the operational voltage is suspended, and thereafter the application of the flight suppressing voltage is suspended. With the control thus carried out, the flight of unnecessary toner is suppressed, thereby ensuring that images of high quality are obtained.

摘要： A laser scanning optical system converts a plurality of beams emitted from the laser diode (LD) into parallel light using a collimator lens, shapes the parallel light using an aperture, and executes exposure of a plurality of lines simultaneously on a photoreceptor drum. To cause a necessary emitting point interval d determined uniquely from the magnification of the optical system to coincide with an emitting point interval of the LD used, the LD is rotated by an angle θ against the main optical axis plane thereof. In this case, a converting device that converts the aspect ratio of a profile of the light beam emitted from the LD is provided. A conversion characteristic of the converting device is adjusted such that the characteristic is matched with a condition within a predetermined region following a characteristic of the optical system.

摘要： A control device for a straddle-type vehicle includes a first storage means configured to store a target cruise control speed, and a first detection program which senses if the vehicle accelerator is operated in the further closing direction from the totally closed position of the accelerator. The control device also includes a deceleration processing program which decreases the stored target cruise control speed when the first detection program detects the further closing operation during cruise control. The deceleration processing program varies the rate at which the stored target cruise control speed is decreased according to the magnitude of the operating force utilized in the further closing operation.

摘要： A doctor blade is provided in contact with frictionally charged toner in a toner tank, which regulates the amount of toner held on a toner holder. A charge control unit supplies to the doctor blade a voltage for selectively charging the toner. As a result, the amount of toner held on the toner holder is regulated, and simultaneously, the toner is charged to a specific polarity with a potential of the frictional charge or more. An electrostatic latent image is formed by the selectively charged toner. The toner is moved and transferred onto a papersheet which is sequentially transported, under the influence of an electric field generated by application of a voltage to an opposite electrode disposed opposing the toner holder. An image by the toner is thus formed on the papersheet.

摘要： A motorcycle sets a target slip value based on an accelerator operation by a driver, and prevents a significant decrease in the output torque of the drive power source during execution of traction control to provide a comfortable ride. The motorcycle includes a target slip value calculating section that calculates a target slip value, based on an accelerator operation by a driver; and an actual slip value calculating section that calculates an actual slip value, based on the difference between the rotation speed of the front wheel and the rotation speed of the rear wheel. The motorcycle further includes a drive power source controller arranged and programmed to reduce the output torque of the drive power source, based on the difference between a criterion value different from the target slip value and the actual slip value when the actual slip value is lower than the target slip value.
