A method is provided that determines authenticity of a second recording medium mounted in a second device by using a first device mounted with a first recording medium. A non-user area of the first recording medium previously records first identification information and first algorithm data. A controller of the first recording medium causes a first display device to display a first image pattern and, after display of the first image pattern, causes a first imaging device to capture a second image pattern displayed on a second display device of the second device. The controller decodes first code data from the second image pattern and utilizes the first algorithm data to perform arithmetic that uses the first identification information and a first variable value.

Image forming apparatus

This invention relates to an image forming apparatus that, in film formation processes, reduces toner consumption in the toner image pattern of an image while suppressing detection errors in the adhesion detection mechanism. The image forming apparatus forms a toner image pattern, such as a scraping toner pattern (Kp), which is input to a cleaning component, such as a cleaning squeegee, used to clean the surface of an image carrier (e.g., an intermediate transfer belt), without transferring it to a recording medium. This toner image pattern is a long strip-shaped pattern in an orthogonal direction to the surface movement direction of the image carrier. Furthermore, the toner image pattern is formed by a method in which the input toner dose to a location corresponding to the placement position of the adhesion detection mechanism (e.g., an optical sensor (40F, 40C, 40R) of the cleaning component) is greater than the input toner dose to a location not corresponding to the placement position of the cleaning component.
