An image forming device having a rotatable medium, a latent image forming device for forming a latent image on the rotatable medium, apparatus for applying liquid developer to the latent image to form a toner image, apparatus to transfer the toner image to transfer material and a cleaning apparatus for cleaning the rotatable medium after transfer. The device is operated so that there is an initial application of developer to the cleaning apparatus to loosen any dried toner after which the rotatable medium undergoes a prerotation of at least one half of a complete rotation before image formation is begun.
