IMAGE FORMING APPARATUS WITH FUNCTION TO MEASURE GLOSS LEVEL

摘要

An image forming apparatus includes a fixing unit, a gloss level measuring section, and a fixation condition setting section. The gloss level measuring section measures a gloss level of an image portion and a gloss level of a non-image portion in a recording medium after fixation, and separately measures, as the gloss level of the image portion, a first gloss level indicative of a gloss level of a chromatic toner image and a second gloss level indicative of a gloss level of a black toner image. The fixation condition setting section sets the fixation condition for the fixing unit so that the first gloss level and the second gloss level approach respective different target gloss levels, on the basis of a measured value of the first gloss level and a measured value of the second gloss level and a measured value of the gloss level of the non-image portion.
