Abstract: 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.

Abstract: A developing device includes a first screw that supplies a developer to a developing roller while agitating/conveying the developer in a first direction, and a screw that collects residual developer from the developing roller, agitates/conveys the residual developer in a second direction opposite to the first direction, and delivers the residual developer to the first screw. Between two points that a magnetic flux density in a normal direction of a magnetic field formed in a developer separating magnetic pole in the developing roller become substantially zero, a point at a downstream side in a rotating direction of the developing roller is formed at an upstream side to a developing roller rotating direction, than a line joining the center of the developing roller and the center of the second screw.
