Abstract

PURPOSE:To minimize the reduction of initial picture concentration and maintain the picture concentration at an optimum value even if the number of reproduction is increased by installing metallic members contacting with a wide area of the conductive supporting element of a sensitive material and attaching a procedure to make airflow around the sensitive material. CONSTITUTION:Plural baglike metallic members 3 contacting with a wide area of a conductive supporting member are installed inside a sensitive element and these metallic members contact wich each other and both ends of them are contacted with a holding plate 2. An outer plate 4 is installed so as to surround the sensitive element 1 and plural air holes 4b are equipped on one side 4a of the outer plate 4. A shutter tube 5 is attached so as to surround the air holes 4b and an air feeding hole 5b is formed on the side of the shutter tube 5. A discharging hole 4a is formed on the other side 4c of the outer plate 4 and a fan is arranged inside the outer plate close to the discharging hole 4d to make air flow around the sensitive element 1. Thus, the picture concentration can be maintained at an optimum value.
