Abstract:
1. An inkjet printer comprising: a recording head including a nozzle through which ink is jetted onto a recording medium; and an ultraviolet ray irradiation device including an ultraviolet ray light source which generates an ultraviolet ray to cure the ink after it is jetted onto the recording medium to form an image, wherein the ultraviolet ray irradiation device comprises a cover member arranged to cover the ultraviolet ray light source, the cover member having a plurality of interior surfaces exposed to the ultraviolet ray light source, a first one of the surfaces being situated relative to the ultraviolet ray light source and the recording head such that ultraviolet rays are reflected by the first surface to the nozzle of the recording head, and wherein means are arranged in connection with the first surface for reducing the reflectance of ultraviolet rays from the ultraviolet ray light source to the nozzle of the recording head such that the reflectance of ultraviolet rays by the first surface is lower than the reflectance of ultraviolet rays from remaining surfaces of the cover member.
