1. An image forming apparatus comprising:
a photosensitive body;
a drive unit which drives the photosensitive body;
an intermediate transfer body which is wound around the photosensitive body, the intermediate transfer body being driven by the movement of the driven photosensitive body;
a latent image forming unit which forms an electrostatic latent image on the photosensitive body according to image information;
a plurality of development units which develop the electrostatic latent image on the photosensitive body with toners respectively having different colors;
a holding unit which holds the plurality of development units, the holding unit causing the development units to sequentially face the photosensitive body;
a transfer unit which transfers a toner image from the photosensitive body to a portion of the intermediate transfer body where the intermediate transfer body is wound around the photosensitive body; and
a drive speed control unit which controls the drive unit of the photosensitive body according to density of the toner image to be formed on the photosensitive body.
