    • The present invention provides a method for manufacturing a film for a film capacitor in which a film can be prepared by melt extrusion molding in a thin film having a thickness of 10 μm or less and in which a cost can be cut by simplifying a manufacturing step thereof and a film for a film capacitor. It is a method for manufacturing a film for a film capacitor comprising the steps of charging a melt extrusion molding equipment 10 with a molding material 1 to mold a film 20 for a film capacitor by extruding from a dice 12, interposing the above extruded and molded film 20 for a film capacitor between a pressing roll 31 and a metal roll 32 to cool it and winding up the cooled film 20 for a film capacitor having a thickness of 10 μm or less in order on a winding tube 41 of a winding device 40, wherein the molding material 1 is prepared by adding a fluorocarbon resin to a PEI resin having a glass transition point of 200° C. or higher and a dielectric breakdown voltage of 100 V/μm or more; and a uniaxial elongational viscosity of the above molding material 1 is controlled to a range of 6,000 to 20,000 Pa·s.

    • An image forming apparatus includes a developing device that uses a developer carrier to advance to an image carrier a developer including a toner and a carrier and supplies the toner to the image carrier by applying a developing bias between the developer carrier and the image carrier. In the image forming apparatus, the following operation is performed before the developer in the developing device is taken out. The toner is supplied to the image carrier by applying the developing bias between the developer carrier and the image carrier, the developing bias increased in a direction to supply the toner to the image carrier. The toner supplied onto the image carrier is not transferred to a transfer receiving material but is advanced into a toner recovery device for recovery. The recovered toner is prevented from being returned to the developing device.
    • 图像形成装置包括显影装置,该显影装置使用显影剂载体将图像载体前进到包括调色剂和载体的显影剂,并通过在显影剂载体和图像载体之间施加显影偏压将调色剂供应到图像载体。 在图像形成装置中,在取出显影装置中的显影剂之前执行以下操作。 通过在显影剂载体和图像载体之间施加显影偏压将调色剂供应到图像载体,显影偏压在向调色剂供应到图像载体的方向上增加。 供应到图像载体上的调色剂不转印到转印接收材料上,而是进入调色剂回收装置以进行回收。 回收的调色剂被阻止返回到显影装置。
