摘要： An image forming apparatus includes a photoreceptor, an exposure device for exposing the photoreceptor with a laser beam dot by dot so as to form a dotted latent image on the photoreceptor, and a developing device for developing the dotted latent image with developer. The apparatus also includes a dot diameter correcting device for correcting a diameter of the dot formed on the photoreceptor. The dot diameter correcting device includes an image patch producing device for forming an image patch having a specific dot pattern with a laser beam having a predetermined power strength by the exposure device, an image patch detector for detecting a density level of the image patch formed on the photoreceptor, and a memory for storing data of laser power strengths with correlation to the detected density levels. With this structure, a controller controls laser power strength of the exposure device based on the correlated data stored in the memory and the density level detected by the image patch detector.
