A fixing device includes a fixing unit, a shearing unit, a detection unit, and a controller. The fixing unit fixes a toner image in place on a printed surface of a recording medium. The shearing unit is disposed downstream from the fixing unit along the media conveyance path to at least partially shear toner from the fixed toner image, so as to create a shorn image area that exhibits a different image density than that of an intact, unshorn image area on the printed surface of the recording medium. The detection unit is disposed at least partially downstream from the shearing unit along the media conveyance path to measure the image densities of the shorn and unshorn image areas. The controller is operatively connected to the fixing unit and the detection unit to adjust one or more operational parameters according to a difference between the measured image densities.
