Abstract: An image forming apparatus for forming an image corresponding to a subject is provided, which image forming apparatus includes a taking lens for making an optical image corresponding to the subject, and a dividing portion for dividing the optical image transmitted via said taking lens into several adjacent optical image parts. The image forming apparatus further includes several solid-state image sensors corresponding to the number of the optical image parts, each of said solid-state image sensors receiving a corresponding optical image part from among the several optical image parts from the dividing portion and outputting an image signal corresponding to the optical image part, the optical image parts received by said solid-state image sensors being adjacent to each other.
