<p>PURPOSE:To easily and efficiently form a high-accuracy color image by refracting light beams emitted by light emitting elements which differ in wavelength through a prism, and converging them on a recording carrier one over another on one and the same line. CONSTITUTION:A photosensitive material F is exposed by 1st LEDs 56a and 56b, 2nd LEDs 58a and 58b, and 3rd LEDs 60a and 60b mounted on the exposure head. Then the light beams LC, LM and LY emitted by the respective LEDs are refracted by the prism 40 and superposed one over another on the same line. Namely, the light beams LC, LM and LY are refracted by the prism 40 and superposed one over another on one end the same line by selecting the angle positions of the 1st LEDs 56a and 56b, 2nd LEDs 58a and 58b, and 3rd LEDs 60a and 60b for the prism 40 according to the refractive indexes to the light beams LC, LM and LY. Consequently, color blurring is precluded and the color image with superior accuracy is easily and securely formed.</p> |
