An image scanning apparatus, including a contact glass having an original to be scanned on; a light source including plural dotted light-emitting elements linearly arrayed in a main scanning direction and emitting scanning light to the original; a photoelectric converter photoelectrically converting reflected scanning light from the original to produce line-image data in the main scanning direction; a halation detector receiving the line-image data from the photoelectric converter and detecting whether the line-image data has halation; and a corrector receiving information whether the line-image data has halation and correcting pixel values of all pixels of the line-image data having halation into a predetermined pixel value.
