An image forming apparatus includes a paper feed device and an image forming apparatus main body including a paper feed cassette removable from the image forming apparatus main body and including an image forming unit. The paper feed cassette stores a recording material, and the image forming unit forms an image on the recording material. The paper feed device allows the image forming apparatus main body to be stacked on the paper feed device below the paper feed cassette. The paper feed device is provided with a coupling section. In a space formed in a case where the paper feed cassette is removed from the image forming apparatus main body, the coupling section is fixed to the image forming apparatus main body by a fixing unit to couple the image forming apparatus main body and the paper feed device together.
