In an image forming device, in a case where a storage medium is connected to an input output interface, and a storage medium stores import instruction information including a plurality of setting values, a controller imports a target value from the storage medium to a memory. The plurality of setting values is associated with respective ones of a plurality of pieces of device-specific information. The target value is a setting value selected from the plurality of setting values and is associated with a piece of device-specific information unique to the image forming device. Each of the plurality of setting values associated with respective ones of a plurality of pieces of device-specific information is for setting a prescribed parameter of a corresponding device. After the target value is imported, the controller operates according to the target value set for the prescribed parameter.
