Patent ID: 7065314

Claim:
An image forming apparatus comprising: an engine which performs an image forming process in which a toner image is formed by developing a latent image on a latent image carrier by means of any one of a plural developers that is positioned at a predetermined development position, and transferred onto a toner image carrier moved in a given moving direction; and a controller which selectively carries out a monochromatic print mode, in which a monochromatic image is formed by performing said image forming process for a specific color, or a color print mode in which a color image is formed by the steps of forming plural toner images by performing said image forming process at each changeover of plural developers and of superimposing said plural toner images on top of each other on an image carrier, wherein said engine arranges N images, wherein n>2, on said toner image carrier along said moving direction, and said controller adjusts a first spacing between the M-th image and the (M+1)-th image, wherein M represents a natural number of less than N, so that said color print mode and said monochromatic print mode are different from each other in said first spacing.
