Abstract: PURPOSE:To obtain superior antistatic effect without causing adverse effect on the photographic characteristics even under severe developing conditions such as sensitivity increasing treatment, rapid processing treatment, etc. by incorporating a polymer having specified recurrent units in an antistatic layer provided in a photosensitive material. CONSTITUTION:The polymer having recurrent units expressed by the formula (wherein R1-R3 are alkyl, aralkyl, or at least two thereof joint to each other forming an N- contg, heterocyclic ring; n is 1-10; X<-> is an anion) is incorporated in the antistatic layer comprised of at least one layer.

By providing such layer, generation of static electricity is retarded, influencing no adverse effect on a photosensitive material even if it is treated to have elevated sensitivity. No adverse influence is effected on the photographic characteristics even under severe condition such as rapid processing, etc. By this method, great efeffect is resulted on a usual black and white silver halide sensitive material, multilayered color photograhic sensitive material, particularly on the sensitive material for rapid processing at high temp., and highly sensitized sensitive material.

Abstract: PURPOSE: To minimize a deviation of manufacturing conditions and an influence of working temperatures by forming a constant current circuit with resistor and  Zener diode having such diffusion layers as are equal in impurity density and  distribution.  
     CONSTITUTION: P-type diffusion layers 2 and 3 are formed on the surface of N-type semiconductor substrate 1, and diffusion layers 4a and 4b which are equal in impurity density and distribution are formed on the diffusion layers 2, 3 respectively. Thus zener diode is constituted between the diffusion layers 2 and 4a. On the other hand, a resistance is constituted between the diffusion layers 3 and 4b. Then, the diffusion layers 2 and 3 are connected electrically, a load is connected between the  diffusion layers 4a, 4b, and a voltage is applied between both terminals of Zener  diode. Where the voltage exceeds Zener voltage of the Zener diode, a current  flowing in the load can be kept constant. Furthermore, since the diffusion layers  4a and 4b are equal in impurity density and distribution, an influence of change  in manufacturing conditions or temperatures can be minimized.
