An image-forming device comprises an identifier-storage unit for storing an identifier in correlation with one of a plurality of feeding units on which at least one sheet used for image-forming processing is loaded, a specification unit for specifying the feeding unit by using the identifier, and a usability-determination unit for determining whether use of the specified feeding unit is permitted, where the image-forming device forms an image by feeding the sheet from the specified feeding unit based on the determination result made by the usability-determination unit.
