Abstract
An edge wear reducing pressure roller is provided and comprises (a) a roll member having a cylindrical elastomeric outer layer including a longitudinal axis and a length having a first position for supporting a first edge of a copy sheet and a second position for supporting a second edge of the copy sheet; and (b) a cylindrical core located within the cylindrical outer layer also having the longitudinal axis, and a length for supporting the cylindrical elastomeric outer layer. The cylindrical core includes a first segment having a first diameter, and a second segment having a second diameter less than the first diameter for creating variation in elastomeric layer thickness. The second segment advantageously is located directly underneath the first position for supporting the first edge of the copy sheet, and the second position is advantageously located underneath the second position for supporting the second edge of the copy sheet.
