There is provided a retrieval memory that can easily manage address information. A retrieval memory which retrieves whether or not inputted retrieval data matches entry data stored in a memory cell array and outputs address information corresponding to matched entry data includes a plurality of retrieval blocks and an output control unit for outputting the address information. The address information includes a block address for specifying at least one of the retrieval blocks and a logical address corresponding to entry data in the specified retrieval block. The output control unit outputs address information that is reset so that the address information corresponding to the entry data becomes continuous in an address space based on a size of the entry data.

Two identical images are printed, side by side, on an intermediate transfer-recording medium, by using image data that represents an image to be printed on a brochure. The two images thus printed are compared, thereby to determine whether they have defects. One of the images, which is found to have no defects, is transferred from the intermediate transfer-recording medium to the brochure, which is a final transfer-recording medium.
