An LED printer is an electro-photographic printer using LED print head (LPH). The LPH consists of LED array and Gradient-Index (GRIN) array [1]. Figure 1 (a) shows a configuration of LED printer. The GRIN array projects an erected unit magnification image of the LED array on the photoconductor. Figure 1 (b) illustrates the LPH. The GRINs are arranged at larger interval than that of LEDs. The GRIN has a field view larger than its arrangement interval. The images by the GRINs are superposed on the image of one LED as shown in Fig. 2.
