Abstract:

To provide a printing head which can effectively utilize light emitted from a light source, and an image formation device having the printing head.

The printing head 3 has the light source 531, and a light guide body 52 which can emit the light emitted from the light source 531 from a light emission face 522 extended in a main scanning direction while causing the light to advance in the main scanning direction. The outgoing light emitted from the light emission face 522 is irradiated to a photosensitive recording medium 22. A condensing layer 502 is set at a point corresponding to the light emission face 522, which can condense the outgoing light to reduce a tilting angle of the outgoing light with respect to a normal of the light emission face 522.
