Abstract
An image forming device comprises a print head in which an array pitch of organic EL elements arranged in a main-scanning direction is at least twice the size of a light-emitting portion of one organic EL element, an aperture diameter of a microlens is no more than the array pitch, and the aperture diameter has an area that is larger than that of the light-emitting portion of the organic EL element. After the exposure of a photosensitive material onto the emitted light from the organic EL element, the photosensitive material is moved for each movement by moving the print head in the main-scanning direction by a predetermined amount to fill a space between exposure spots at which mutually adjacent organic EL elements are focused, and divide exposure of one main-scanning line of the photosensitive material into a plurality of exposures without leaving any space.
