  • Patent number: 8623582
    Abstract: A method of treating a photoconductor for enhancing crack resistance when it comes into contact with a liquid toner comprises bending a photoconductor sheet having a length and a width to a tube having an outer diameter and a length corresponding to the width of the photoconductor sheet with the photoconductive layer facing outward. The tube of the photoconductor sheet is then inserted into a cylinder having an inner diameter greater than the outer diameter of the tube and a length of at least the length of the tube of the photoconductor sheet. The treatment of the tube of the photoconductor sheet in the cylinder takes place by maintaining it in the cylinder at a temperature of from about room temperature to an elevated temperature. The tube of the photoconductor sheet is removed from the cylinder while it is at about room temperature.
