Abstract: At an initializing operation, if it is determined that an indirect transfer film has not been replaced before power-on if transferred sensor marks are detected while being conveyed from a supply spool to a winding spool, then the unused amount of the indirect transfer film is estimated on the ratio between the rotation angle of the supply spool and the rotation angle of the winding spool, if the unused amount is estimated to be 2% remaining amount alert threshold or more, positioning of the primary transfer is performed based on the last sensor mark among the sensor marks, and if estimated to be less than 2% it is determined that the unused amount is greater than an amount necessary for recording on the next recording medium unless an end mark is detected while the indirect transfer film is conveyed by predetermined image areas from the last sensor mark.
