A photosensitive body for electrophotography having improved properties in the charging characteristics, photosensitivity, and stability in repeated use. The photosensitive body for electrophotography comprises a photoconductive layer formed on a conductive support through an undercoat layer, the undercoat layer containing at least one polyester compound having repeated units represented by the following general formula (I): ##STR1## wherein A and B each independently represents a divalent aliphatic hydrocarbon or aromatic hydrocarbon which is optionally substituted, at least one of A and B being selected from the group consisting of specific divalent groups, and n is 10-10,000.
