Abstract
An image forming apparatus includes a plurality of photosensitive members, charging devices provided respectively with the photosensitive members to charge the photosensitive members, an exposing device for exposing the charged photosensitive members to image light, developing devices for developing electrostatic images on the photosensitive members with toners of different colors, a transfer device for sequentially conveying a toner image carrying medium to the transfer-positions of the photosensitive members and transferring the toner images of different colors to overlap each other on the toner image carrying medium, and a color mixing device for mixing the colors of the stacked toner images. The charge amounts of the toners for developing the electrostatic images on the photosensitive members are substantially equal.
