摘要： A color image forming apparatus according to the invention includes an intermediate transfer member for transferring a color image onto a paper sheet, a second transfer roller capable of directly transferring, onto a paper sheet, a toner image formed on a photosensitive member to transfer a black-and-white image onto a paper sheet, a first transfer roller for transferring, onto a paper sheet, a color image on the intermediate transfer member. Since the process of transferring a black-and-white image onto a paper sheet is separated from the process of transferring a color image from the intermediate transfer member, a black-and-white image can be transferred onto a paper sheet and fixed thereon immediately after development. Thus, the period required for copying a black-and-white image, in particular, the required first copying period of a black-and-white image can be shortened.
