PURPOSE:To render an electrophotographic sensitive body exposable after it is positively charged electrostatically by positive corona discharge by using a photosensitive layer contg. 3 components of a specified perylene pigment, polyvinyl carbazole, and an electron attractive dye. CONSTITUTION:The same photosensitive layer disperses or dissolves 3 components of a perylene pigment represented by formula I , and poly-N-vinyl carbazole, and an electron attractive dye represented by formula II in which X, X', X'' are each halogen; Y is -COOH or -SO3H; Z, Z' are each H, halogen, -NO2, -CN, -OR, -COR, or 0NRR'; R, R' are each 1-3C alkyl; l is 0 or an integer of 1-4; n, m are each an 0 or an integer of 1-3 satsifying n+m>=4; and p, q are each 0 or an integer of 1-2. |
