发明名称 IMAGE FORMING APPARATUS AND IMAGE DENSITY CONTROL METHOD
摘要 An image forming apparatus including an image carrier; an intermediate transfer member having a first portion and a second portion that has a higher glossiness than that of the first portion; a primary transfer member; a light source to emit light to the intermediate transfer member side; a detector to detect intensity of reflected light emitted from the light source and then reflected from the intermediate transfer member and a density adjustment pattern formed on the intermediate transfer member; a processor including a light-emission intensity adjuster to adjust light-emission intensity from the light source based on detected intensity of light reflected from the second portion of the intermediate transfer member; and an image forming condition controller to control image forming conditions for forming a toner image based on the detected intensity of the light reflected from the density adjustment pattern formed on the intermediate transfer member.
