ABSTRACT:
An image forming apparatus includes a photoreceptor, a driving unit which rotation-drives the photoreceptor, an exposure unit which forms a latent image by performing image exposure to the photoreceptor, a plurality of development units which develop a plurality of latent images sequentially formed on the photoreceptor with different color toners respectively, a belt-like intermediate transfer member onto which respective color toner images sequentially developed on the photoreceptor are primarily transferred to be superimposed on each other, at least one load unit which comes in contact with or is separated from the belt-like intermediate transfer member to change a load on the belt-like intermediate transfer member, and a speed control unit which increases/decreases a driving speed of the photoreceptor at a specified timing. Preferably, the belt-like intermediate transfer member is an elastic belt.
