Abstract
An optical print head and an image formation apparatus which can form a satisfactory image without shortening an exposure time in an image processing at high speed. A satisfactory image is formed at high speed by alternately radiating a first light emitting element array and a second light emitting element array under a predetermined driving condition depending on a relation between a distance d in a Y direction between elements perpendicular to an array direction X of light emitting elements and an image resolution pitch P by using the optical print head composed of two light emitting element arrays.
