摘要： An image forming apparatus includes a conveyance unit to convey an image carrier and an image forming unit to form an image on the image carrier. The image forming apparatus also includes a first determining unit, a control unit, an irradiation unit, an output unit, and a second determining unit. The first determining unit determines a first image forming condition of the image forming unit for forming a heavy line image at a particular width and thickness. The control unit causes the image forming unit to form a first measurement image having a particular width and length. The irradiation unit emits light onto the image carrier. The output unit outputs a first signal corresponding to a thickness of the first measurement image by receiving reflected light. The second determining unit determines a second image forming condition for forming a fine line image at a particular width and thickness.
