    摘要: An oil application roller unit including a holder having at least a shaft or bearings, an oil application roller rotatably supported by the holder, and an oil leakage prevention film closely wound around the oil application roller to pack the roller and capable of being pulled out. By pulling the oil leakage prevention film while the oil application roller remains installed in the holder, the oil application roller is rotated, and the oil leakage prevention film can be removed. Since the user is not required to make contact with the oil application roller at the time of unpacking, the hands of the user are not stained. Unpacking can thus be attained safely.

    摘要: As a cooling mechanism that cools the entire paper passage area of a heat-producing belt, a rotational drive method of the heat-producing belt is employed and the heat-producing belt is cooled by rotational cooling by being made to idle when paper is not being passed through. An excitation apparatus and the above-described cooling mechanism are controlled so that recording paper is not passed through and the heat-producing belt is cooled while being heated over the heating width when the small-size recording paper is passed through until the temperature detected by a paper non-passage area temperature detecting sensor is at or below a predetermined fixing temperature. This fixing apparatus enables an excessive rise in temperature of a paper non-passage area of the heat-producing belt to be efficiently eliminated, and the temperature distribution of heat-producing belt to be made uniform in a short time.

    摘要: An image heating apparatus that enables a temperature of an image heating element to be stably maintained at a target temperature as a fixing speed varies. A Proportional-Integral-Derivative (PID) controller determines whether a temperature control computation results in a range that allows temperature control with one IGBT, and a linear control is performed if the result is at least equal to a minimum power obtained as IH output. PWM control is performed at minimum power if the power is less than a required minimum power. Thus, a computation method of a supply power computator need not be switched according to the fixing speed, and a calorific value of a fixing belt can be controlled using one computation method.

    摘要: A fixing apparatus is provided that enables a recording medium that has undergone heat-fixing to be separated smoothly from a heating medium without causing a sheet jam or image disturbance. In this apparatus, there are provided on the guide surface of a separator two step parts raised along the guide surface guide width direction. Recording paper is transported gripped by a fixing nip, is guided so as to come into contact with only the apex parts of step parts, and is separated from the surface of a fixing belt. Thus, a gap is formed between the guide surface and the heat-fixing surface of recording paper guided along the guide surface, the contact area between the heat-fixing surface of recording paper and the guide surface decreases, the heat-fixing surface of recording paper becomes less prone to adhere to the guide surface of the separator, and recording paper is smoothly separated from the fixing belt without causing a sheet jam or image disturbance.

    摘要: An image heating apparatus is provided that enables the temperature of an image heating element to be maintained stably at a target temperature even when the fixing speed varies, and that enables lower cost and higher efficiency to be achieved. In this apparatus, with a calorific value control section 300 of a fixing apparatus 200, temperature control computation is not varied according to the rotational speed of a fixing belt 230, but it is determined whether a PID control computation result is in a range that allows temperature control with one IGBT, linear control is performed if the result is greater than or equal to the minimum power obtained as IH output, and PWM control is performed at minimum power if power less than or equal to the minimum power is required. It is thus not necessary for the computation method of a supply power computation section 301 to be switched according to the fixing speed, and the calorific value of fixing belt 230 can be controlled with one computation method. Therefore, the supply power to the heat source of fixing belt 230 can be PID-controlled by only one switching element (IGBT), lower cost and higher efficiency can be achieved, and the temperature of fixing belt 230 can be maintained stably at the target temperature.

    摘要: An image forming apparatus and a process cartridge capable of satisfying both a high quality image and an excellent maintenance property with a simple configuration. A photosensitive member and a charging roller that is a member rotating in contact with the photosensitive member are brought into contact with each other in the image forming process. When an image forming operation starts from a standstill, the charging roller is rotated before the photosensitive member starts to be rotated. Furthermore, before the photosensitive member stars to be rotated, a reversed bias voltage that is a voltage opposite to the bias voltage at usual development time is applied between the members rotating in contact with the photosensitive member and the photosensitive member. The time for which the charging roller is rotated before the photosensitive member starts to be rotated is set to be 0.01-2.0 seconds and is changed in accordance with the number of pages printed and is reduced each time the number of pages printed reaches a predetermined number.
