    摘要: An image forming apparatus includes a recording unit, a detecting unit, a designating unit, a comparing unit, and a control unit. The recording unit records an image onto a recording medium. The detecting unit detects the size of the recording medium. The designating unit designates a size of a recording medium onto which an image is to be recorded. The comparing unit (1000) compares the detected size with the designated size to determine which size is larger. The control unit (1100) controls the apparatus to perform operations such that an operation when the detected size is larger than the designated size is different from that when the detected size is smaller than the designated size.
