An image detector for use has a constitution of serial lamination of a first stripe electrode, a first rectifying layer with multiple photodiodes which takes on conductivity upon receiving irradiation of recording light, a second rectifying layer with multiple diodes of a reverse polarity to the first rectifying layer, and a second stripe electrode. Upon recording, a voltage is applied between the first stripe electrode and the second stripe electrode, whereby uniform electric charges are accumulated in the capacitor. Then, the recording light is irradiated from the first stripe electrode side, so that electric charges for a latent image on the capacitor are annihilated in accordance with a dosage of the recording light. Upon retrieval, a given voltage is applied between each of elements on the first stripe electrode and elements on the second stripe electrode, whereby a charged currents flowing into the image detector 10 is detected.
