Abstract: An image forming apparatus includes a transfer member, first transfer units, and second transfer units. Images of reference colors and other colors are transferred onto the transfer member being rotated. The first transfer units each transfer the image of a corresponding one of the reference colors. The second transfer units disposed upstream of the first transfer units in a rotational direction of the transfer member each transfer the image of a corresponding one of the other colors. The image of one of the reference colors is transferred by one of the first transfer units disposed most upstream. The other colors include at least one color of lightness lower than lightness of the one of the reference colors of the image transferred by the one of the transfer units. The highest-lightness image among the other colors is transferred by one of the second transfer units disposed most downstream.

Abstract: An image forming apparatus includes a transfer member, plural transfer sections, and a medium transfer section. The transfer member has an endless shape. An image is transferred to the transfer member during circulation of the transfer member. The transfer sections transfer the image to a surface of the transfer member through a first transfer current. The transfer sections include a most-downstream transfer section provided most downstream in a circulation direction of the transfer member. The medium transfer section transfers the image transferred to the transfer member to a recording medium through a second transfer current. A current flows through the most-downstream transfer section even in the case where the image is transferred to the transfer member by at least one of the transfer sections excluding the most-downstream transfer section, and the most-downstream transfer section does not transfer an image to the transfer member.
