Zusammenfassung: | PROBLEM TO BE SOLVED: To solve a problem that a tracing pattern different from the substantial tracing pattern is superimposed when a memory storing tracing pattern information is replaced in an image forming device superimposing a tracing pattern onto an image. SOLUTION: An image processing section 401 in a printer controller is provided with a nonvolatile memory 553, a pattern attachment section 402 in a printer engine is provided with a nonvolatile memory 556 and when attached data information items stored in both the memories are dissident, the image forming device forms no normal image. |
