<p>PROBLEM TO BE SOLVED: To position relative location with high accuracy and thereby form images with high quality without the need of being enlarged in size, complicated in its structure, and highly increased in cost by installing an exposure system and image carrier body on common support members. SOLUTION: The support members 16, 16 are common support members with an LED head unit 8 (herein, accompanying characters: a, b, c, d are omitted because of the same as in Y, M, C, K) and a photosensitive drum 7 installed in position, and made into a unitary part coupled by a stay. Also, the device is provided with a flanges 17, 18 secured by a press-insertion method in both ends of the photosensitive drum 7, a shaft 19 disposed energizably through an electrification board on the photosensitive drum 7, a positioning pin 50 of the LED head unit fixed on the support member 16 corresponding to the longitudinal direction side of the LED head unit 8, and an attaching standard pin 52 for attaching the photosensitive drum formed on the support member 16. A fitting hole 53 for the shaft 19 is made on the support member 16 in the same axial line as the pin 52.</p> |
