Abstract: A color image forming apparatus of the present invention is, for example, a digital color copying machine arranged to include two image processing units (first and second image processing units) each having a photosensitive body. The first image processing unit forms a monochrome image and the second image processing unit forms a particular pattern or a trace pattern. According to this arrangement, the particular pattern or trace pattern can be added to a monochrome image while maintaining a printing rate as fast as a monochrome image printing rate. Consequently, an additional information of a color other than black can be combined with a monochrome image at the same printing rate as the monochrome image printing rate, thereby making it possible to provide a compact and inexpensive apparatus.

This printer includes a wrapping material storing section for storing a wrap film, which is a wrapping material for wrapping an article. There is a clock for measuring time to generate time data, and an output for recording the time data on the surface of the wrap film. When the wrap film is discharged from the wrapping material storing section, the output records the time data on the surface of the wrap film. Therefore, on the wrap film with which the article such as food is wrapped, the time data, for example, the date and time when this food was wrapped are recorded. Thus, a user can check accurately the date and time the wrapping occured.
