Claim:
1. An image reading apparatus comprising: a front surface reading sensor configured to read a front surface of a document; a rear surface reading sensor configured to read a rear surface of the document; a storage control unit configured to store, in a same memory, image data of the front surface of the document read by the front surface reading sensor and image data of the rear surface of the document read by the rear surface reading sensor; and an encoding unit configured to perform encode processing on each basic unit in a pair image data of the front and rear surfaces generated by the image data of the front surface and the image data of the rear surface, wherein a file format of a file generated by the encoding unit is a predetermined file format having a possibility that mutual interference occurs around a boundary of a plurality of pixels adjacent to each other at the time of the encode processing, wherein the storage control unit stores image data of an end position of the image data of the front surface in the main scanning direction and a space in a first basic unit on the memory and stores image data of a start position of the image data of the rear surface in the main scanning direction in a second basic unit, different from the first basic unit, on the memory, for generating the file of the predetermined file format.
