Claim:
1. An edge detection apparatus for detecting an edge of a recording medium to be conveyed, comprising: a light source that irradiates the recording medium with light; a plurality of photoelectric conversion element pixels that are placed in a direction orthogonal to a conveyance direction of the recording medium and convert the light reflected by the recording medium into an electrical signal; and a detector that detects the edge of the recording medium based on a plurality of electrical signals that constitute an n-th (n≧1) electrical signal group obtained by dividing the plurality of electrical signals corresponding one-to-one to the plurality of photoelectric conversion element pixels, and a specified number of the electrical signals counted from a top of the plurality of electrical signals that constitute an n+1st electrical signal group, wherein the detector receives a parallel input of:
