摘要： An image forming apparatus includes an image bearing member for carrying a toner image; an image forming unit for forming a toner test image on the image bearing member; a transfer material carrying member, for carrying a transfer material, wherein the test toner image is transferred onto a transfer material carried on the transfer material carrying member or onto the transfer material carrying member; and a density detecting unit for detecting a density of the toner test image transferred to the transfer material carrying member. A transfer intensity is smaller when the toner test image for density detection is transferred onto the transfer material carrying member than when the toner test image is transferred onto the transfer material tarried an the transfer material carrying member. The transfer intensity also changes depending on whether the transferred toner test image is the first color toner test image or the second toner test image, and depending on an ambient condition sensor.
