<p>PURPOSE:To obtain the electrophotographic device which can use light emitting elements with small chip area, enables their individual replacement even if the light emitting element has variance in light emission intensity, enables the light emitting elements to be arrayed on conditions that their intervals are sufficient, reduces the width of a carriage where the light emitting elements are mounted, and uses a small-sized, lightweight, inexpensive, and low-output driving motor. CONSTITUTION:A shift block 74 is provided on the surface of a photosensitive body 1 across a light guide 7. This shift block 74 is supported by a block 5a, a leaf spring 5b, etc., and LEDs 3 having one light emission part for each chip are arrayed across the carriage in parallel in the direction of the rotary shaft of the photosensitive body 1. This shift block 4 is moved by feeding electricity to a piezoelectric element and the LEDs 3 are blinked to form an electrostatic latent image on the surface of the photosensitive body 1.</p> |
