<P>PROBLEM TO BE SOLVED: To obtain an optical printhead, in which the relative positional relation between a light emitting element and an imaging element is stable and excellent imaging states are maintained, its joint structure, an assembly method for the optical printhead, and an image forming device. <P>SOLUTION: A light emitting element array support member 4, to which a light emitting element array composed by linearly arranging a plurality of the light emitting elements is installed, and an imaging element array support member 6, to which an imaging element array composed by linearly arranging a plurality of the imaging elements, are joined by a photocuring adhesive 11 after deciding the mutual positional relation. A joint strength improving means, which is composed of an optical reflecting means for enhancing the adhesive strength by the photocuring adhesive 11, is provided. The joint strength improving means is an irregular reflection surface 12 of the light which is formed at least on one adhesive face of the light emitting element array support member 4 and the imaging element array support member 6. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
