    摘要： An image forming apparatus, includes an image forming mechanism configured to form an image, and a fixing unit configured to fix a toner image formed on a recording medium. The fixing unit includes a fixing device having a first endless moving member configured to rotate, and a second endless moving member configured to rotate to form a nip area together with the first endless moving member to fix, at the nip area, a toner image disposed on the recording medium onto the recording medium with heat and pressure, the second endless moving member including a surface layer having a universal hardness HU and a maximum nip surface pressure P each within a predetermined range.

    摘要： A fixing apparatus includes a fixing member to be heated and a pressure-contacting member for pressure contacting the fixing member. The fixing apparatus directs and conveys a recording member through a nip formed between the fixing member and pressure applying member in such a manner that a toner image carried on a recording member contacts the fixing member in order to be fixed thereto with heat and pressure. The fixing apparatus is configured to direct a tip margin of the recording member toward the pressure applying member across a virtual linear extension line drawn from a downstream end to upstream end of the nip when only the tip margin exits from the nip. A fixing member side separation device may be separately provided from the surface of the fixing apparatus so as to separate the recording member exiting from the nip. A gap formed between the downstream end of the nip and the tip of the fixing member side separation device is set smaller than the width of the tip margin.
