    摘要: A fixing device includes a pressing rotary body pressed against a fixing rotary body to form a fixing nip therebetween through which a recording medium bearing a toner image is conveyed; a heater to heat the fixing rotary body, disposed opposite a circumferential surface of the fixing rotary body and upstream from the fixing nip a predetermined circumferential distance along the circumferential surface of the fixing rotary body in a direction of rotation of the fixing rotary body; a heater driver to turn on and off the heater; a timing calculator to calculate a reference time at which a trailing end portion of the recording medium in a conveyance direction of the recording medium reaches the fixing nip; and a heater driver controller to cause the heater driver to turn off the heater at a turn-off time earlier than the reference time.

    摘要: An image forming apparatus includes a fixing device disposed downstream from an image forming device in a recording medium conveyance direction to fix a toner image formed by the image forming device on a recording medium. The fixing device includes a pressing rotary body separatably pressed against a fixing rotary body to form a nip therebetween through which the recording medium bearing the toner image passes, and a moving assembly to move the pressing rotary body bidirectionally to press the pressing rotary body against the fixing rotary body and separate the pressing rotary body from the fixing rotary body. A controller controls the moving assembly to change a post-fixing pressing time period for which the moving assembly presses the pressing rotary body against the fixing rotary body after the recording medium bearing the toner image is discharged from the nip according to image data.
