Abstract
When a predetermined pattern (e. g. a pattern indicating the serial number of a copying machine) is added on an image formed on a recording paper, the image formation apparatus according to the invention suppresses fog appeared by addition of the predetermined pattern in the vicinity of the image. More particularly, a control circuit which inputs and processes an image signal estimates the leading and ending edge position of the recording paper with respect to the transferring direction and the edge which is perpendicular to the transferring direction of the recording paper based on the signal obtained from an ITOP generation circuit and BD detector. Accordingly, an effective area for image formation on the recording paper is obtained and the modulation amount for adding the predetermined pattern is controlled in accordance with the position on the recording paper to which the predetermined pattern is outputted.
