Organic photosensors were investigated by using x-type metal free phthalocyanine(x-H<sub>2</sub>Pc) photoconductor. The desired values of some properties in the photosensor of 200dpi(dot per inch) resolution linear imagesensor for facsimile were examined. The photosensor comprising of Pb electrode of low workfunction metal which is in contact with the x-H<sub>2</sub>Pc layer was recognized to be Schottky barrier. The relative darkcurrent of photosensors with Pb electrode of Schottky barrier and Au electrode (high workfunction metal) of ohmic contact were measured.<br>The darkcurrent value of Pb electrode was reduced by about 10<sup>3</sup> than that of Au electrode. The highest photoresponse time was observed by Pb electrode photosensor. It was clarified that the photoresponse times depended on the workfunction of electrode metals of the photosensor.<br>Photocurrent property of the photosensor with the Pb electrode of low workfunction indicated ohmic current, while the photocurrent of the photosensor with the Au electrode of high workfunction indicated space charge limited current. The results of photocurrent (1.1×10<sup>-6</sup>A), photo-to-dark current ratio (7×10<sup>4</sup>), photoresponse rise time(0.6ms) and decay time (0.9ms) were obtained by constructing the photosensor, ITO/x-H<sub>2</sub>Pc/Pb These results may be used for linear imagesensor of 200dpi.
