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.

摘要： An image forming apparatus has an image bearing member, an intermediary member and a voltage applicator to electrostatically to transfer the toner image from the image bearing member onto the intermediary transfer member and then transfer the image onto a transfer material. The apparatus is operable selectively in a first mode in which toner images of different colors are sequentially and superposedly transferred from the image bearing member onto the intermediary transfer member by the voltage application, and in a second mode in which only a toner image of a first color of the different colors is transferred onto the intermediary transfer member from the image bearing member. An absolute value of the voltage applied to the intermediary transfer member by the voltage applicator is larger when the second mode is selected than when the first mode is selected, when the toner image of the first color is transferred from the image bearing member onto the intermediary transfer member.
