    摘要： An electrophotographic photoconductor has a conductive substrate and a photosensitive layer on the substrate. The photosensitive layer contains a compound represented by the formula (I), 1 wherein X is selected from the group consisting of a single bond, O, CO, and COO, each of R1 and R2 is independently selected from the group consisting of an optionally substituted aromatic hydrocarbon group, an optionally substituted aliphatic hydrocarbon group, a polycyclic aromatic ring represented by formula (Ia), and a heterocyclic ring represented by formula (Ia), 2 wherein Y represents a residual group to form said polycyclic aromatic ring or said heterocyclic ring, and said substituent being selected from the group consisting of a hydroxyl group, a cyano group, a nitro group and a halogen atom. The resulting electrophotographic photoconductor exhibits reduced residual potential after charging and exposure to light, and therefore facilitates high quality imaging.

    摘要： The invention provides a method of forming an image on a photoreceptor indicating a maximum value of the differential coefficient to the exposure in the light decay curve thereof. The method comprises charging the surface of the photoreceptor; exposing uniformly the surface of the photoreceptor at the same time or substantially at the same time with the step of the charging; forming a latent image on the surface of the photoreceptor by a dot-wise image exposure; and developing the latent image on the surface of the photoreceptor.
