An embodiment of a document processing apparatus that has a function of correcting image scanning resolution according to the present invention includes a first carriage mounted with a first reflector that reflects reflected light from a document fixed on an original placing glass plate in a predetermined direction and a second carriage mounted with a second reflector that changes a direction of incident light from the first reflector by 180°. A correction distance from a default position of the second carriage with which predetermined resolution is obtained in plural scanning positions of the first carriage is calculated.
