Abstract:
1. A method for transferring a toner image from a latent image carrier to a transfer image carrier, comprising: running the latent image carrier at a reference running speed VA and running the transfer image carrier at a reference running speed VB, wherein VA=VB; and transferring the toner image from the latent image carrier to the transfer image carrier while controlling at least one of the latent image carrier and the transfer image carrier in such a manner that a relative speed ΔV between the latent image carrier and the transfer image carrier is changed to positive and negative sides of an average reference running speed V, where V=VA=VB, wherein the transferring includes controlling either one or both of the latent image carrier and the transfer image carrier in such a manner that the relative speed ΔV varies in approximately a sinusoidal wave shape, with respect to time, around the average reference running speed V.
