LIGHT SOURCE DEVICE FOR IMAGE FORMING APPARATUS

PROBLEM TO BE SOLVED: To provide a light source device for an image forming apparatus, where a laser element and an optical member are firmly attached to a holder with a photocurable resin. SOLUTION: The light source device 8 for an image forming apparatus includes: the laser element 1 that emits a laser beam; a laser element holding member 10 that holds the laser element 1; the optical element 2 that shapes the laser beam; and the holder 9 that holds the laser element holding member 10 and the optical element 2. The holder 9 includes: an end opening 14 that opens one side in the optical axis direction of the inner wall 11 by holding at least either of the laser holding member 10 and the optical element 2 between two opposing inner walls 11 with a gap from the inner wall 11, with the photocurable resin separately heaped up on the inner wall 11; and a side opening 15 that opens one side in a direction perpendicular to the optical axis of the inner wall 11.
