Abstract
To provide an image forming device that is capable of preventing deterioration of the image quality through preventing deterioration of the toner even if frequency of making a copy is low. The image forming device includes: a developing part having a developing roller for achieving development by electrostatically attaching a toner onto an electrostatic latent image formed on a photoreceptor; a transferring part for transferring a developed toner image to a paper; and a cleaner part for removing and collecting the toner remained on the photoreceptor after transferring, wherein the developing roller is rotary-driven at a lower speed than a speed of development under a standby state. The image forming device includes a standby-state refresh control part for forcibly consuming an amount of the toner that is calculated based on accumulated time of the low-speed rotary drive.
