PURPOSE:To provide the titled equal magnification sensor having high response speed, excellent photocurrent/dark current characteristics and long length, by placing individual electrodes, a common electrode and a photo-conductive material containing a specific hydrazone compound and a specific azo dye as active components on an insulating substrate. CONSTITUTION:The objective equal magnification sensor can be produced by attaching individual electrodes and a common electrode to the surface of an insulating substrate (e.g. glass plate) and covering the insulating substrate with a photo-conductive material containing a hydrazone compound of formula I (R1 is methyl, ethyl, etc.; R2 is methyl, ethyl, phenyl, etc.; R3 is H, Cl, Br, 1-4C alkyl, etc.) and one or more azo dyes of formula II [A is group of formula III (Ar2 is benzene ring, naphthalene ring, etc.), etc.], formula IV, formula V (Ar is phenyl, pyridyl, etc.), formula VI (X is benzene ring, indole ring, etc.), formula VII, etc., as main components by dipping method, etc. |
