Abstract
Photoconductor drum having a hollow cylindrical base element with a coating on the outer surface including at least one photosensitive layer, the base element concentrically accommodating at least one core element which is made at least partially cylindrical and which is made at least partially of plastic, the core element on its outer surface which comes into contact with the inside of the base element having irregularities or roughness.
Claims11
A photoconductor drum comprising a hollow cylindrical base element having a coating on an outer surface, said coating comprising at least one photosensitive layer, the base element concentrically accommodating at least one core element, the core element having an outer surface having irregularities contacting an inside of the base element, wherein the irregularities are formed by knurling to form rough annular nubs.
The photoconductor drum as claimed in 1, wherein the rough annular nubs surround cylindrical or conical depressions.
A photoconductor drum comprising a hollow cylindrical base element having a coating on an outer surface, said coating comprising at least one photosensitive layer, the base element concentrically accommodating at least one core element, the core element having an outer surface having irregularities contacting an inside of the base element formed by knurling wherein the core element has a rough annular molded attachment on at least one end side.
A photoconductor drum comprising a hollow cylindrical base element having a coating on an outer surface, said coating comprising at least one photosensitive layer, the base element concentrically accommodating at least one core element, the core element having an outer surface having irregularities contacting an inside of the base element, wherein the irregularities are formed by knurling and the core element has a weight in the range from 40 and 150 g.
