A film having an imprinted antenna, for use with an RFID chip. The determination unit determines an amount of correction of an image clock for controlling an output timing of a beam for each pixel constituting one line in a main scanning direction of the beam. These mutants and the DNAs encoding them are expected to be useful as therapeutic agents, or employed for gene therapy against hyperphosphatemia. The monitored loads and position are compared with the safety limit; and the movement of the selected MTB stopped when either the desired load transfer is completed or the safety limit has been met. The surface information detecting device radiates optical spots on a surface of the fixing member in a direction crossing a conveying direction, receives reflected light of each optical spot, and detects the surface information of the fixing device based on the detection results of the reflective lights.
