Image forming apparatus capable of undergoing remote image diagnosis, control method therefor, and storage medium storing control program therefor

Abstract

An apparatus that enables an operator to easily perform an image diagnosis by ascertaining an analysis image that does not include an unnecessary image and that reduces a user's superfluous indication. A forming unit forms an image on a sheet. An image reading unit reads image data from an original. An output processing unit outputs a second analysis image that is obtained by adding a predetermined image pattern to a first analysis image for an image diagnosis to a sheet with the forming unit. A read processing unit reads the sheet on which the second analysis image is output with the image reading unit and generates first image data. An analysis unit analyzes the first image data. An erasing unit generates second image data that is displayed for the image diagnosis by erasing the predetermined image pattern from the first image data.
