<p>An image forming apparatus (1) including a sheet container (2), a sheet stacking member (3) to closably open the sheet container (2); a restriction unit (13; 103) to restrict a swinging movement of the sheet stacking member (3), and a stopper mechanism (230A; 230B; 230C) to restrict insertion of the sheet container (2) into the image forming apparatus (1) in a state in which the sheet stacking member (3) swings open from the sheet container (2). The stopper mechanism (230A; 230B; 230C) includes a stopped member (231A; 231B; 231C) provided to the sheet container (2) and being movable vertically along the swinging movement of the sheet stacking member (3), and a stopper member (241A; 241B; 241C) provided to the image forming apparatus (1) and being contactable with the stopped member (231A; 231B; 231C). The stopped member (231A; 231B; 231C) includes a stopped surface (239) contacted by the stopper member (241A; 241B; 241C) in a state in which the stopped member (231A; 231B; 231C) is lifted; and a switching surface (238) adjacent to the stopped surface (239) and vertically moving the stopped member (231A; 231B; 231C) by contact against the stopper member (241A; 241B; 241C).</p> |
