To perform sure erasion by improving throughput without requiring useless processing time in the case of photographing with plural kinds of sensitivity.

In this method where a radiation image is read, the read (S4) the erasion (S5) of a stimulable phosphor plate where radiation image information is accumulated and recorded are performed by moving a reading means or the stimulable phosphor plate. In the case of photographing with high sensitivity, a reading and erasing means is moved before photographing (S3) so as to add the erasion of the stimulable phosphor plate (S2).
