Abstract
An image forming apparatus for performing a series of image forming operations, comprising an exposure unit for exposing the photosensitive recording medium to an image light to form a latent image thereon in a first exposure process, a pressure-developing unit for superposing the photosensitive recording medium over a developer medium under pressure to form a visible image on the developer/medium, sheet feeding rollers for feeding the photosensitive recording medium through the exposing unit and the pressure-developing unit in forward and reverse directions to thereby perform sheet feeding and rewinding operations, respectively, the photosensitive recording medium being fed back in the rewinding operation after pressure-developed by the pressure-developing unit to dispose an unexposed area of the photosensitive recording medium in the first exposure process to a predetermined position where the unexposed area is subjected to a second exposure process subsequent to the first exposure process, and a control unit for ceasing all of the image forming operations when any abnormality occurs during at least one of the image forming operations, wherein the control means controls the sheet feeding means to continue the sheet rewinding operation irrespective of occurrence of the abnormality if it is judged that the abnormality does not disturb the sheet rewinding operation.
