Patent ID: 8131168

Claim:
An image forming apparatus, comprising: a photosensitive member having a surface to which a latent image is formed; a charging section which charges the surface of the photosensitive member; an exposure section which irradiates a light onto the surface of the photosensitive member charged by the charging section to form the latent image; a developing section which supplies toner onto the latent image formed on the surface of the photosensitive member to form a toner image; an intermediate transfer member to which the toner image formed on the surface of the photosensitive member is transferred; a transfer section which transfers the toner image onto the intermediate transfer member; a density detection section which detects a density of the toner image transferred to the intermediate transfer member; a density correction section which executes density correction processing of the toner image forming in a case where a density value detected by the density detection section does not satisfy a predetermined condition; a toner accumulation section that supplies toner to the developing section; a toner remaining amount detector which detects a toner remaining amount of the toner accumulation section; and a determination section which determines that failure has occurred in the exposure section if the density value detected by the density detection section does not satisfy the predetermined condition after the density correction processing by the density correction section is terminated and the toner remaining amount detected by the toner remaining amount detector is greater than a predetermined remaining amount.
