摘要： A release layer, which contains fluoropolymers is applied on a die surface of a shaping die, and is baked. An elastic layer is applied onto the external surface of the release layer and is baked. A supporting layer containing heat-resistant synthetic resin is applied onto the external surface of the elastic layer, and is dried. The dried supporting layer is polished to remove the unevenness, and the supporting layer is baked. The release layer, the elastic layer and the supporting layer are turned inside out to be removed from the die surface. The evenness of the fixing belt is improved, and the pressure unevenness is reduced.

摘要： An image forming apparatus has a toner carrier and a toner passing control having a plurality of toner passing holes for controlling passage of a toner. The toner passing control has upstream side secured, the downstream side extended by a spring, and is contacted with a stay on the downstream side of the contact point with the toner carrier, so that corrugation deformation is prevented. A vibrating plate and an ultrasonic vibration generator are coupled through a coupling portion, thereby relative displacement between the vibrating plate and the ultrasonic vibration generator is allowed. A detachable toner cartridge is formed by integrating a developing roller and a toner storing container.

摘要： In a color electrophotographic printer, an intermediate transfer belt is provided to layer toner images of a plurality of colors, and the toner images on the belt are transferred onto a paper sheet. In order to remove a paper sheet when a paper jam happens, a door is provided in a case of the printer, while a cover is provided to protect a transfer region where the intermediate transfer belt contacts with a paper sheet for transferring the toner images. When the door is opened, the cover moves to cover a portion of the surface of the intermediate transfer belt exposed to the door. When the jammed paper sheet is removed, the image forming process is resumed immediately on the toner images on the intermediate transfer belt. Further, an intermediate transfer unit including the intermediate transfer belt and the cover detachable from the printer may be provided. In a modified example, a transfer member which is connected to a transfer member is provided instead of the cover, and when the door is opened, the transfer member covers the surface of the intermediate transfer belt.
