Abstract
In an electrophotographic image forming apparatus, the density of a dot image is stabilized by detecting the toner density of a first standard toner image having toners of a uniform density formed on a photoconductor, adjusting the development bias voltage applied to a development device according to the detected toner density. The adjusted development bias voltage is used to form on the photoconductor a second standard toner image having toners of dots with predetermined spaces there between. Then, an area ratio of dot area to unit area of the second standard toner image is detected and is used to control the image forming conditions of the image forming apparatus to stabilize the density of a dot image.
