Patent ID: 8615174

Claim:
An image forming apparatus comprising: a latent image carrier to carry a latent image thereon; an image information obtaining unit to obtain image information; a latent image forming unit to form a latent image based on the obtained image information; a developer carrier to carry developer formed of toner and carrier thereon; a developing device to cause the developer to be carried on the surface of the developer carrier to a developing area in which the developer carrier and the latent image carrier are opposed, and develop the latent image by adhering the toner of the developer onto the latent image carried on the latent image carrier; a toner replenishing device to replenish toner to the developing device; a controller to adjust a toner replenishment amount by controlling drive of the toner replenishing device based on the image information; and a nonvolatile memory to store information of an amount of the toner replenishment amount which has not been replenished, wherein when the developing device enters a stopped state, information relating to the amount of the toner replenishment amount which has not been replenished is stored in the nonvolatile memory, and when the developing device resumes a driven state from the stopped state, driving of the toner replenishing device is controlled using the information stored in the nonvolatile memory.
