Abstract: An image forming apparatus connectable to a first feed tray and a second feed tray includes an image forming unit, a feed path, and a detecting unit provided on the feed path to sense recording medium jam. An identifying unit identifies a feed path and a feed tray where recording medium jam has occurred as a jammed path and a jamming feed tray. A first determining unit determines whether the image forming apparatus is connected to the second feed tray. A second determining unit determines whether the second feed tray can feed a recording medium to the image forming unit. A feeding unit feeds a recording medium from the second feed tray to the image forming unit.

Abstract: An image reading apparatus having a memory to store therein image data acquired by reading an original is provided. In a regular reading mode, the memory is divided into a first buffer that stores therein first image data of an image of a first side of the original and a second buffer that stores therein second image data of an image of a second side of the original. In a ring buffer mode, only the first image data is stored in the first buffer and the second buffer in a seamless manner, and the first image data stored in the buffers is output from the buffers to an image processing unit through an output path in a parallel manner. When a size of an original to be read is larger than a predetermined size, reading is performed in the ring buffer mode.
