PURPOSE: A curing apparatus for a printer using an LED is provided to improve the quality of a printed object by irradiating ultraviolet rays with uniform optical energy distribution to an area in which ink is jet. CONSTITUTION: A curing apparatus for a printer using an LED comprises multiple Light Emitting Diodes(114) and a bifocal lens(120). The LEDs are installed inside a housing(110). The bifocal lens is arranged under the LEDs. The curvature of the center of the bifocal lens is smaller than the curvature of the periphery part of the bifocal lens. A cooling fan(116) is arranged on the LEDs. Masks(122) with through holes are arranged under the bifocal lens.
