Abstract: PROBLEM TO BE SOLVED: To provide a recorder which is high in a recording grade free from pseudo contour lines, etc., even when paper of a size larger than the size of the paper used in executing density unevenness correction is subjected to printing. SOLUTION: An image region deciding circuit 112 decides the printing part of a recording head 109 from the image information of a test pattern for density correction on a material to be recorded which is read by an input sensor section 101. A correction value calculating circuit 113 calculates the density correction value of each of respective recording elements of the recording head from the data of the part decided to be the printing part of the recording head. An off-region correction value determining circuit 114 determines the correction value even for the elements on the outer side not actually printed on the material to be recorded at the time of the density unevenness correction in accordance with the calculated correction values.  A correction circuit 107 corrects the printing density characteristics by each of the respective recording elements in accordance with these correction values. As a result, the pseudo contour parts (density level differences) between the part subjected to the correction and the part not subjected to the correction or the like may be prevented.
