An image forming apparatus includes a stopping part, a mode deciding part, a changing part and a type distinguishing part. The stopping part temporarily stops print execution if a type value indicating a type of a sheet conveyed according to the print execution is not included within a given range. The mode deciding part decides whether or not a mode set in the print execution is a specific mode using a different sheet from a sheet used in normal print condition. The changing part changes, if the mode set in the print execution is the specific mode, a width value used for distinguishing the sheet type to a first width value smaller than a normal width value. The type distinguishing part measures the type value and decides whether or not the type value is included within a threshold range defined by the changed width value. |
