。 In a paper feed cassette that has a double-feed prevention claw that presses the leading edge of paper to prevent double-feeding of paper, a shape memory alloy is used to move the double-feed prevention claw to the first position to hold the leading edge of the paper, and to the leading edge of the paper. When the paper feed cassette is installed in the main body of the image forming apparatus, the double feeding prevention claw moves the shape memory alloy from the second position to the first position. A paper feed cassette characterized in that it is transformed so as to be displaced and the double feed prevention claw is returned from a first position to a second position when the paper feed cassette is removed from an image forming apparatus main body.
