Description
本発明の実施形態は、画像形成装置に関する。 Embodiments of the present invention relate to an image forming apparatus .
本発明が解決しようとする課題は、熱変色性紫外線硬化型インク用のインクジェット式画像形成装置を提供することである。 The problem to be solved by the present invention is to provide an inkjet image forming apparatus for thermochromic ultraviolet curable ink.
一方、上記で説明した熱変色性紫外線硬化型インクは、水ベースのインクであるため、熱変色性を示す顔料を、色変化機能を保持したまま安定してインク中に保持することができる。また、上記で説明したインクは、水ベースのインクであるため、有機溶剤ベースの従来の紫外線硬化型インクと比べて、低い粘度を有する。このため、上記で説明したインクは、加熱することなくインクジェットプリンタで吐出させることができる。 On the other hand, since the thermochromic ultraviolet curable ink described above is a water-based ink, it is possible to stably retain the thermochromic pigment in the ink while maintaining the color changing function. Further, since the ink described above is a water-based ink, it has a lower viscosity than conventional ultraviolet curable ink based on an organic solvent. Therefore, the ink described above can be ejected by an inkjet printer without being heated.
このように、上記で説明したインクは、色変化機能に優れるとともに、インクジェット記録において高い吐出安定性を実現することができる。また、上記で説明したインクは、高い吐出安定性を有するため、優れた印字性を実現することができる。加えて、上記で説明したインクは、紫外線硬化型であるため、優れた定着性を実現することができる。 As described above, the ink described above has an excellent color change function and can achieve high ejection stability in inkjet recording. Further, since the ink described above has high ejection stability, excellent printing performance can be achieved. In addition, since the ink described above is of the ultraviolet curing type, excellent fixing properties can be achieved.
また、実施形態に係るインクジェット式画像形成装置は、上記効果を奏する熱変色性紫外線硬化型インクを記録媒体へ吐出して、インク層を形成し、その後、インク層を乾燥させ、更に紫外線照射により定着させる。このため、実施形態に係る画像形成装置は、上記で説明したインクと同様の効果を奏することができる。すなわち、実施形態に係る画像形成装置は、高い吐出安定性、優れた印字性、および優れた定着性を達成することができる。また、定着された画像は、優れた色変化機能を示すことができる。更に、実施形態に係る画像装置は、インクの吐出時に加熱動作を必要としないという利点を有する。 Further, the inkjet image forming apparatus according to the embodiment forms an ink layer by discharging the thermochromic ultraviolet curable ink that exhibits the above effects onto a recording medium, then dries the ink layer, and further irradiates the ink layer with ultraviolet rays. Make it stick. Therefore, the image forming apparatus according to the embodiment can achieve the same effects as the ink described above . That is, the image forming apparatus according to the embodiment can achieve high ejection stability, excellent printing performance, and excellent fixing performance. Additionally, the fused image can exhibit excellent color change capabilities. Furthermore, the image device according to the embodiment has the advantage of not requiring a heating operation when ejecting ink.
