    摘要: The invention is related to an electrophotographic photoreceptor, its preparation, and its use in electrophotography. The instant photoreceptor comprises a conductive substrate and a photosensitive layer containing an organic pigment as a charge generating material, wherein said organic pigment is formed from a soluble organic pigment precursor. Particularly suitable soluble pigment precursors are of formulae (I) or (XIV), ##STR1## wherein A represents a chromophore residue which is a perylene, quinacridone, dioxazine, anthraquinone, azo, phthalocyanine, isoindolinone, isoindoline, indigo, quinophthalone or pyrrolopyrrole with 1 to 5 N atoms bound to the D.sub.1 and D.sub.2 groups, whereby each N atom of A is independently from the other bound to 0, 1 or 2 groups D.sub.1 or D.sub.2 ; D.sub.1 and D.sub.2 are independently a group represented by the general formula ##STR2## x is an integer from 0 to 4; L.sub.1 and L.sub.2 are independently from one other halogen, alkoxy or amino groups, and M.sub.2 is two hydrogens or a metal or oxometal with at least two valences;as well as derivatives thereof. The instant electrophotographic photoreceptors have hight sensitivity and low residual electric potential and can be obtained without applying any dispersion procedure.
