    摘要： An image forming apparatus includes an image bearing member, an intermediate transfer belt, first, second, and third power sources, and a control unit. During print job execution, the control unit controls the third power source such that a discharge current supplied to the intermediate transfer belt is constant current controlled based on first and second power source current supply detection results. When changing from a first to a second discharge current, the control unit controls the third power source such that, after a first image forming region passes through a primary transfer portion, an intermediate transfer belt trailing edge to which the first discharge current is supplied initially passes through the primary transfer portion and such that, before a second image forming region passes through the primary transfer portion, an intermediate transfer belt leading edge to which the second discharge current is supplied initially passes through the primary transfer portion.

    摘要： A developing device includes a developing container, a developing roller, a supplying roller, a first magnet including a first magnetic pole, a second magnet including a second magnetic pole and a third magnetic pole, a regulating member provided opposed to the third magnetic pole. During non-image formation, an operation in a mode in which the supplying roller is rotated in a direction opposite to a rotational direction of the supplying roller during image formation is executable. With respect to the rotational direction of the supplying roller during the image formation, a position where a magnet flux density of the third magnetic pole in a tangential direction to an outer peripheral surface of the supplying roller is zero is positioned downstream of an upstream end of the regulating member and upstream of the second magnetic pole.

    摘要： An image forming apparatus includes a belt, a first process unit, a second process unit, and a controller configured to form a toner image based on a first pattern on a first photoconductive body of the first process unit. In addition, the controller is configured to transfer the toner image onto the belt, form an electrostatic latent image based on a second pattern on a second photoconductive body of the second process unit such that the electrostatic latent image formed on the second photoconductive body positionally coincides with the toner image transferred onto the belt in a contact position where the second photoconductive body contacts the belt, and convey the electrostatic latent image formed on the second photoconductive body to the contact position without developing the electrostatic latent image with toner.
