摘要： Along a rotational direction of a photoreceptor, a cleaner unit for cleaning a surface of the photoreceptor, a lubricant applying apparatus for applying a lubricant to the surface of the photoreceptor, and a charging device for charging the surface of the photoreceptor are disposed in this order. Further, the lubricant applying apparatus applies the lubricant to the surface of the photoreceptor which has been cleaned and has not been charged. As a result, it is possible to uniformly apply the lubricant to the surface of the image carrier for an extended period of time with stability.

摘要： When the paper size signal indicates small-sized paper, after the final sheet of a consecutive sheet feed operation of that size has passed through the heating device, paired rollers consisting of heat and pressing rollers are actuated to rotate for a predetermined period (rotational mode) while no sheet passes therethrough. After completion of the rotational mode, the paired rollers are stopped from rotating for a predetermined period (stationary mode).

摘要： A periodic disturbance restraining unit 23 is provided with a control component oscillating at a frequency equal to a frequency of a periodic disturbance of a mold level, calculates a mold level periodic disturbance restraining state amount by using a mold level control deviation signal from a control deviation calculating unit 21 and outputs a mold level periodic disturbance restraining signal. A control loop robust stabilization unit 24 receives a mold level steady-state deviation restraining signal from a steady-state deviation restraining unit 22 and the mold level periodic disturbance restraining signal, calculates an operating amount of a stopper so that a mold level control loop of the control apparatus is brought into robust stability and outputs an operating amount signal. A periodic disturbance frequency adapting unit 25 receives a mold level detected value signal and a casting speed detected value signal and detects an oscillatory frequency of the mold level as a periodic disturbance frequency and changes calculation characteristics of the periodic disturbance restraining unit and the control loop robust stabilization unit based on a result of the detection.

摘要： In a fixing device, a sheet of paper carrying an image formed with pre-fixed toner is transported to a fixing nip region in which (1) a fixing roller heated by a heating roller outside of the fixing roller and (2) a pressure roller come into contact, so that the toner is melted and fixed on the sheet of paper. The heating roller is controlled so that a surface portion of the fixing roller in the vicinity of an exit of the fixing nip region constantly has a set temperature during the transport of the sheet of paper through the fixing nip region. By thus arranging a fixing device, the resultant fixing device features a short warm-up period, high thermal efficiency and uniform temperature distribution, capability of fixing color toner without application of oil, durability and safety, a simple structure and a low manufacturing cost, no curling of paper after fixation, and applicability to high-speed printing.

摘要： A fixing device is disclosed for fixing an unfixed toner image onto a sheet of paper by sandwiching in a contacting portion between an fixing roller and a pressing roller, and thus transporting, the sheet carrying thereon the unfixed toner image. The blade includes a base body made from a heat resistant rubber material (e.g., fluororubber) and a fluororesin sheet adhered to the surface of the base body by an adhesive agent so as to cover an edge portion of the blade. This permits provision of a fixing device with an oil-applying function which has superb durability and stability over a long period of time. The fluororesin sheet is preferably a tetrafluoroethylene=perfluoroalkylvinylether copolymer sheet. The adhesive agent is preferably a single component room-temperature-setting type silicone adhesive agent.
