RADIATION IMAGING DEVICE

PURPOSE:To obtain a radiation imaging device which can improve image detection sensitivity and gradation property by making extremely uniform the full electrification level of the entire surface of a sensitized body layer of an image plate which is a body to be electrified to a high voltage. CONSTITUTION:A net-shaped electrode 20 as a conductive net body which is maintained at a specific potential is laid out opposingly near the entire surface of a sensitized body layer 14 of an image plate 10 which is a body to be electrified to a high voltage and at the same time a wire electrode 32 where a high- voltage potential is applied is mechanically scanned at one surface side of the net-shaped electrode 20, thus electrifying the entire surface of the sensitized body layer 14 to a high-voltage potential, for example, by providing an electrifying equipment such as a scorotron electrifying equipment 30.
