Zusammenfassung:	PURPOSE:To improve residual image characteristics by assuring uniform injection of biasing charges into a signal charge storing diode by providing a gate and a diode for injection and discharging of the biasing charges. CONSTITUTION:A signal charge storing diode 10, a signal charge reading part 30, and a signal charge transferring part 20 are formed on a semiconductor substrate, and a gate 40 and a diode 50 both for injecting biasing charges into the signal charge storing diode 10 via the signal charge reading part 30 are provided adjoining to the signal charge transferring part 20. Thus, the biasing charges can be injected into the signal charge storing diode 10 without use of a light source. Hereby, the biasing charges enough to reduce a capacitive residual image can uniformly be injected to improve residual image characteristics.
