    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.
