    摘要： A fixing device includes an image surface side separating member that separates a recording medium from a fixing member; an image surface side conveyance guiding member arranged downstream of the image surface side separating member; a non-image surface side separating member that separates the recording medium from a pressing member; and a non-image surface side conveyance guiding member arranged downstream of the non-image surface side separating member. When the image surface side conveyance guiding member is rotated about its rotation axis so as to be opened or closed, the image surface side separating member is also rotated or slid so as to be opened or closed simultaneously. When the non-image surface side conveyance guiding member is rotated about its rotation axis so as to be opened or closed, the non-image surface side separating member is also rotated or slid so as to be opened or closed simultaneously.

    摘要： A fixing device for fixing an unfixed toner image on a recording medium includes a fixing member, a pressure member, a sheet guide, and a pressure adjusting mechanism. The fixing member heats the unfixed toner image on the recording medium. The pressure member is disposed opposite the fixing member and presses against the fixing member to define a fixing nip through which the recording medium bearing the unfixed toner image passes to fix the unfixed toner image onto the recording medium. The position of the fixing nip is changeable. The sheet guide disposed adjacent to the pressure member guides the recording medium to the fixing nip and moves in conjunction with movement of the pressure member. The pressure adjusting mechanism operatively connected to the pressure member adjusts an amount of engagement of the pressure member relative to the fixing member. An image forming apparatus includes the fixing device.

    摘要： A fixing device includes a fixing rotation body heating and fixing an unfixed image onto a recording medium; a pressing rotation body pressing the recording medium to the fixing rotation body; and a temperature detection unit detecting a temperature of the pressing rotation body. Further, when a predetermined time period elapses since a warm-up operation has started before a temperature detected by the temperature detection unit is equal to or greater than a predetermined temperature or when the temperature detected by the temperature detection unit is equal to or greater than the predetermined temperature before the predetermined time period elapses since a warm-up operation has started, the fixing device determines that the warm-up operation is finished.
