Image reading apparatus

An image reading apparatus comprising:

• an original conveying device that conveys an original;
• a rotating member having an outer peripheral surface on which a plurality of optical sensors are arranged in a matrix;
• and
• a driving device that causes said rotating member to rotate, wherein an image on the original that is conveyed by said original conveying device is read by said plurality of optical sensors on said rotating member while said rotating member is rotated by said driving device such that said driving device causes said rotating member to rotate in the same direction as a conveying direction of the original that is conveyed by said original conveying device and at a circumferential speed approximately equal to a conveying speed of the original that is conveyed by said original conveying device.
