摘要： Image fixing device for use in electrophotographic apparatus, capable of suppressing gloss of fixed toner image, thus stably producing images of high quality and high level of fixing intensity over a long period of time. The fixing device has a fixing roller and a pressing roller which are contacted with each other and rotate to form therebetween a nip through which a paper supporting unfixed toner image is passed to have the toner image fixed to the paper. The fixing roller has a cylindrical core having fine irregularities formed on its surface and a surface layer made of a resin. The surface of the cylindrical core has a greater elastic modulus than that of the surface layer.

摘要： A transfer member transporting section is disposed so as to bring a tip end of a transfer member into contact with a peripheral face of a transfer rotary member before the tip end of the transfer member enters a nip area. A bias power supply has a polarity inverting function of, during a period from a timing when the tip end of the transfer member is brought into contact with the transfer rotary member by the transfer member transporting section, to that when the tip end of the transfer member enters the nip area, applying a voltage of a polarity which is identical with that of a toner, to the transfer rotary member, and after the tip end of the transfer member enters the nip area, applying a voltage of a polarity which is opposite to that of the toner, to the transfer rotary member.

摘要： Disclosed is an electrophotographic photoreceptor in which an organic lubricant is provided on the surface of an organic photoconductive layer or on a protective layer formed on the organic photoconductive layer. Elements of the organic lubricant are partly exposed from the surface of the organic photoconductive layer or the protective layer while the remainder portions of the elements are embedded or fixed by chemical reaction in the surface region of the photoconductive layer or the protective layer so that the exposed portions of the elements of the organic lubricant provides a lubricating surface layer. The lubricating surface layer supresses wear of the photoreceptor thereby enabling the photosensitive layer to withstand a long repeated use without impairing electrophotographic characteristics.
