摘要：
A specified original that is not supposed to be copied is marked with a pattern that is formed by infrared reflected light. A copying apparatus includes a detecting unit for detecting the pattern and determines that an original is the specified original in accordance with the detection by the detecting unit. A copying operation is controlled in accordance with the determination of whether the original is the specified original that is not supposed to be copied.
