IMAGE FORMING APPARATUS |
摘要 |
An image forming apparatus includes: a photoreceptor, a charging unit which charges the photoreceptor; an exposing unit which forms a latent image onto the photoreceptor; a developing unit which develops the latent image to a toner image; a sensor which detects a line width of a toner patch formed on the photoreceptor by the exposing unit and the developing unit; and a controller which changes a background voltage based on the line width detected by the sensor during an image forming operation so that the line width is secured within a predetermined line width. The controller returns the background voltage to value adjacent to an initial setting background voltage and changes the light amount of the exposing unit by a light amount corresponding to a returning amount of the background voltage.
