Abstract:
A sheet detection unit of an image forming apparatus includes a light receiving unit including a plurality of light receiving elements arranged in a sheet feeding direction. A computation processing unit shifts signals from the elements in synchronization with a sheet feeding speed and makes additions, increases a signal change level, and stores the signals in buffers in a result storage unit. A sheet position determination unit detects a position of an edge portion of a sheet being fed based on distribution of data stored in the buffers.
