IPC: G03G15/32
Filed: 2001-11-01
Abstract: PROBLEM TO BE SOLVED: To obtain an imaging apparatus in which the overall size is reduced, color image is made clear and imaging time is shortened. SOLUTION: A large number of switching elements 2 are arranged in the axial direction and the circumferential direction on the surface of a drum 1 to constitute a switching element array.
