摘要： An image forming apparatus includes an image forming unit, a decision unit, an output unit, a control unit, and a setting unit. The image forming unit forms an image on an image bearing member. The decision unit decides a first image forming condition of the image forming unit for forming the image at a width that is wider than a predetermined width. The output unit outputs a signal in accordance with the thickness of the image. The control unit causes the image forming unit to form a measurement image having a width that is narrower than or equal to the predetermined width. The setting unit sets a second image forming condition of the image forming unit so that the thickness of the image that is narrower than or equal to the predetermined width becomes thinner than or equal to the predetermined thickness.

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.
