Abstract
A fixing device for fixing a toner image on a recording medium includes a hollow, fixing rotary body rotatable in a given direction of rotation and a first heater disposed opposite an inner circumferential surface of the fixing rotary body to heat the fixing rotary body. A pressing rotary body is pressed against the fixing rotary body to form a fixing nip therebetween through which the recording medium bearing the toner image is conveyed. A heat conductor, disposed opposite the first heater and the inner circumferential surface of the fixing rotary body, is disconnectably connected to a guide disposed downstream from the fixing device in a recording medium conveyance direction to guide the recording medium discharged from the fixing nip. The heat conductor conducts heat received from the first heater to the guide.
