Abstract
An image forming apparatus of exposing method has two exposure control modes, automatic and manual, and a controlling section to switch the mode from one to another. When the exposure control mode is switched from automatic to manual, the apparatus of this invention controls the median value of the exposing degree range, from which the users may choose, to be equal to the exposing degree determined in automatic mode. However, in case the exposing degree was not determined when in automatic mode or in case there is a signal that tells an exchange of the original, e.g. job interruption, a predetermined value is fixed to be the median of the exposing degree range.
