<p><P>PROBLEM TO BE SOLVED: To provide a method of manufacturing a high-quality elastic roller excellent in mass productivity that cleans a roller in order to remove a foreign substance, abrasive powder, cleaning liquid, or the like from the surface, end surface, and cored bar of the elastic roller, and suppresses an image failure caused by a cleaning failure. <P>SOLUTION: A cleaning method of the surface, end surface, and cored bar of the roller uses a supporting member of the elastic roller. The supporting member has a core/sheath structure, the core and sheath of the supporting member can reciprocate independently in the direction along the axis, the core supports the cored bar of the elastic roller, and the sheath is moved to cover the exposed part of the cored bar. After cleaning the surface, end surface, and cored bar of the roller, gas is sprayed to the part of the elastic roller where the peripheral surface of the cored bar is exposed through a gap opening over the whole circumference of the core and sheath of the supporting member having the core/sheath structure, and the exposed part of the cored bar is covered with the sheath. Then, gas is sprayed on the peripheral surface of the elastic layer by a ring head having an annular slit opened over the whole circumference at a distance having a predetermined interval to the peripheral surface of the supporting member and the peripheral surface of the elastic layer of the elastic roller. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
