Abstract:
A cylindrical blanket comprising:a cylindrical sleeve; an elastic layer disposed integrally with said sleeve by winding and bonding a sheet-form elastic member on and to the outer peripheral surface of said sleeve, said elastic layer having a circumferential length which is less that of said sleeve to thereby form a gap extending in the axial direction between both circumferential ends of said sheet-form elastic member; and a separation preventive member for preventing both ends in the circumferential direction of said sheet-form elastic member from being separated from said sleeve, said separation preventive member being disposed in said gap having a thickness thinner than the thickness of said sheet-form elastic member to form a groove in the outer peripheral surface of said elastic layer in which a portion of the ends of said sheet-form elastic member are exposed.
