ABSTRACT:
In the ink jet recording apparatus, while the formation of an image on the present sheet is in progress, the remaining length-to-rear end Le between the point at which the presence of the sheet is detected by the sheet detection sensor to the rear end of the present sheet and the remaining recording time Tr from the present time point to the time point at which the formation of the image on the present sheet is completed are measured. Further, in the apparatus, the sheet for the next page is supplied from the feed sheet unit when it is found that that the formation of the image on the sheet for the next page is necessary, that the remaining length-to-rear end Le is less than the reference remaining length-to-rear end Lr, and that the remaining recording time Tr is less than the reference remaining recording time TrR.
