摘要： A transfer unit, which transfers a toner image formed on at least one image support to a printing medium, and an image forming apparatus employing the same. The transfer unit includes: an intermediate transfer body to the toner image from the image support, which has a curved transfer surface and an ASKER-A hardness of from about 25° to 40°; a transfer member, which has an ASKER-C hardness of from about 45° to 70°, and which contacts the intermediate transfer body, with a printing medium being interposed therebetween, and transfers the toner image from the intermediate transfer body to the printing medium. The transfer unit may further include: a de-electrifying member having a DC power and an AC power concurrently applied thereto, to de-electrify the printing.
