Abstract
An image forming apparatus wherein a latent image is electrostatically formed on a surface of a photosensitive member and developed by a developing device. In the above image forming apparatus, the reference line image is formed on the surface of the photosensitive member outside the effective image forming area. The width of the reference line image is detected by a sensor. A developing bias voltage applied to the developing device is controllably changed based on the result of detection by a sensor.
