In an image forming apparatus in which a paper feed cassette is attached to a cassette mounting portion of an apparatus main body, a recording medium in the paper feed cassette is fed into the apparatus main body, and recording is performed on the paper feed cassette. The cassette is provided with a convex portion, and the convex portion fits into the cassette mounting portion that allows the paper feed cassette to be attached, forming a recess that allows the paper feed cassette to be inserted. An image forming apparatus, wherein the cassette attaching part is formed with an abutting part against which the convex part abuts and prevents insertion of the paper feed cassette. 2. In an image forming apparatus in which a paper feed cassette is attached to a cassette attachment portion of the apparatus main body, and a recording medium in the paper feed cassette is fed into the apparatus main body and recorded thereon, a convex portion is provided on the cassette attachment portion; The protrusion enters into the paper feed cassette that allows attachment to the cassette attachment part and forms a relief that allows insertion, while the protrusion abuts on the paper feed cassette that does not allow attachment. An image forming apparatus comprising an abutment portion for preventing insertion of the image forming device. 3. An image forming apparatus in which a paper feed cassette is attached to a cassette mounting portion of the apparatus main body, and a recording medium in the paper feed cassette is fed into the apparatus main body and recorded thereon, and the paper feed cassette is provided with a magnet, and the above-mentioned An image forming apparatus, wherein a cassette mounting portion is provided with a magnetic sensing means operated by the magnet, and a stopper that moves by the operation of the magnetic sensing means and prevents insertion of the paper feed cassette.
