Abstract
A heated roller assembly (10) is disclosed having a rotatable roller (12). The roller (12) has a generally cylindrical section (20) with an outer diameter D and includes an inner insulative layer (36) thereover, a conductive layer (38) over the inner insulative layer (36), and an outer insulative layer (40) over the conductive layer (38). The roller assembly (10) also has an inwardly projecting conical portion (22) adjacent the cylindrical section (20) of the roller (12) with the inner insulative layer (36), conductive layer (38) and outer insulative layer (40) respectively thereover. A portion (A) of the conductive layer (38) on the conical portion (22) of the roller (12) is exposed. An external contact body (14) has at least one electrically conductive outer surface (46) that projects towards and contacts the conductive layer (38) of the conical portion (22) while piercing an imaginary plane P1 formed by an extending outer diameter (D) of the cylindrical section (20). A wire (18) having one end connected to the outer surface (46) of the contact body (14) delivers electricity to heat the roller (12).
