摘要:
A paper feed path is formed along a substantially vertical plane whereby a transfer sheet is subsequently passed through image forming units vertically stacked for subsequent image forming process in each image forming unit. An opening and closing portion of each image forming unit is separated from a main body portion by the paper feed path and is arranged to move about the vertical rotating axis on one side of the paper feed path to open and close the paper feed path in the horizontal direction irrelevant to the vertical stack of the image forming units.

An image forming apparatus having a plurality of image forming units and a sheet transporting unit for transporting sheets discharged from an arbitrary one of the image forming units to a discharge portion of its own or to that of other image forming unit. When one of the image forming units is incapable of continuous operation during the execution of an operation thereof, another image forming unit is operated in place thereof which feeds recording sheets of the same size as those of the former image forming unit and forms images with toner of the same color as that of the former image forming unit, and the image bearing sheets discharged from the latter image forming unit are discharged onto the same discharge portion as that of the former image forming unit.

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.
摘要:
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.

摘要:
When extrusion of a molten resin by means of an extruder is started, a simple polyetherimide resin is melt extruded from a lip portion 7a of a T-die 7, and a film of the simple polyetherimide resin is molded. The molding material is then switched to a resin composition including the polyetherimide resin and a fluorine resin and then a film of the resin composition is continuously extruded and molded from the T-die 7. Having been covered with a very thin film 8a of the simple polyetherimide resin, on a flow passage face of the lip portion 7a of the T-die 7, a resin composition layer 8b including a polyetherimide resin and a fluorine resin, which has affinity with the film 8a, is then formed at a center part.
