Image forming device

Abstract

Abstract PURPOSE:To accurately eliminate the irregularity in density by a method wherein when density of an edge part of a test pattern corresponding to an edge part area of a plurality of ink discharge parts, erroneous information to be obtained from an area near the edge part of the test pattern to be read from density information which a read means obtained, is removed. CONSTITUTION:A harmful influence that an image to be recorded with recording elements at both ends thickness is approximately prevented by replacing a received light quantity data of a part to be measured as thinner density than actual density of a recording image by an influence of a flare with a spatially nearest quantity data among nonproblematic light quantity data. However, since this replacing system does not obtain actual density information of the density at the edge part, a level that irregularity in density is corrected by an ideal correcting process to reach uniform density can not be occasionally obtained. Therefore, an operation in which light quantity data of parts A' and B' to be influenced by a flare are replaced with a value supposed from data near alpha, beta is carried out. Concretely, light quantity data of parts A'' and B'' are made closely akin to a straight line by a method of least squares, and a data obtained by extrapolating said straight line is used.
