摘要： An electrophotographic copying machine of the type in which the copying machine is separated into two sections including a photoreceptor, a developing device, a supporting device for rotatably supporting the developing device so that the developing device is rotated as automatically being separated from the photoreceptor according to the self-weight of the developing device when the copying machine is separated into the two sections. Either the developing device or the photoreceptor can be replaced without damaging the surface of the photoreceptor at all.

摘要： A fixing device for fixing images of an original document on a copy material is provided for a plain paper copier. The fixing device comprises a pair of rollers for stressing under pressure the copy material carrying toner powder thereon. The toner powder is tightly adhered to the surface of the copy material to correspond to the images of the original document. In a preferred form, the toner powder is a pressure-fixable developing powder which consists of a wax component and a thermoplastic resin. A developing powder supplier is disposed within a developer powder reservoir for supplying developer powder to a magnet brush. A rotatable cylindrical magnet is provided within said developing powder supplier for generating a non-uniform magnetic field to stir the developer powder within the reservoir. A copy sheet stripping device is also provided which moves in synchronization with the approach of a copy sheet towards the fixing device and to move in synchronization with the separation of the copy sheet away from the fixing device.

摘要翻译： 为普通纸复印机提供用于将原稿的图像固定在复印材料上的定影装置。 定影装置包括一对辊，用于在压力下施加在其上承载调色剂粉末的复印材料。 调色剂粉末紧密地粘附到复印材料的表面上以对应于原稿的图像。 在优选形式中，调色剂粉末是由蜡组分和热塑性树脂组成的压力定影显影粉末。 将显影剂粉末供应器设置在用于将显影剂粉末供应给磁体刷的显影剂粉末储存器中。 在所述显影粉供应器内设置有可旋转的圆柱形磁体，用于产生不均匀的磁场以搅拌储存器内的显影剂粉末。 还提供了复印纸剥离装置，其与复印纸朝向定影装置的方向同步地移动，并且与复印纸离开定影装置的分离同步地移动。

摘要： A couple of copy sheet stripping members are provided for scraping away a copy sheet adhered strictly to one of two rollers which are driven to fix images of an original document on the copy sheet in pressure engagement. At least one of the copy sheet stripping members is secured removably from the roller while the copy sheet is not transferred out of the rollers. The copy sheet stripping member becomes pressed against the roller in accordance with the transferring of the copy sheet which is detected by a sensing means. The copy sheet stripping member is free of residue attached on the roller because the period of time where the engagement between the roller and the copy sheet stripping member is kept is very short. The other copy sheet stripping member can be further disposed to assure both the scrape of the copy sheet and the removal of the residue on the roller, the copy sheet stripping member being continuously pressed against the roller.
