<P>PROBLEM TO BE SOLVED: To provide a cleaning member that prevents fixation of a matter deposited on a member to be cleaned. <P>SOLUTION: The cleaning member 122 is formed of, for example, a core body 122A (shaft: an example of a base material) and an elastic layer 122B arranged on the outer periphery of the core body 122A. The elastic layer 122B is formed of an urethan foam having an open-cell structure whose hardness based on JIS K 6400-2 (2004) method D is 75-175 N, density is 50-80 kg/m<SP POS="POST">3</SP>, and a ratio between the hardness and the density (hardness/density) is 1.5-3. <P>COPYRIGHT: (C)2012,JPO&INPIT |
