Abstract
In a solid state radiation detector provided with a sub stripe electrode, an S/N ratio is improved. In an electrostatic recording medium, a first current detection circuit is connected to each line electrode of a stripe electrode and a second current detection circuit is connected to each line electrode of a sub stripe electrode. Upon retrieving an electrostatic latent image, electric currents flowing on the respective line electrodes are detected. In addition, signal synthesizing means synthesizes a signal detected by the first current detection circuit and a signal inverted from a signal detected by the second current detection circuit.
