Patent ID: 7668482

Claim:
A sticking substance removing apparatus for removing a sticking substance sticking on a surface of an appointed rotating body, said apparatus comprising: a contacting member having an elongated shape and a first surface and a second surface, wherein said contacting member is fixed at a side of a first end and is not fixed at a side of a second end and contacts said rotating body through said first surface at said side of said second end; and a supporting section which supports said contacting member at least at an upstream side of a contact position between said rotating body and said contacting member with respect to a rotation direction of said rotating body, wherein said supporting section is formed so as to not contact said contacting member at least in an area of said second surface which is opposite to a contact part of said rotating body and said contacting member, wherein said supporting section includes two supporting areas to respectively support said contacting member at said upstream side and at a downstream side of said contact position between said rotating body and said contacting member with respect to said rotation direction of said rotating body, and wherein when setting a straight line distance corresponding to said contact part of said contacting member and said rotating body as a distance “a”, setting a contact point approximately in a center of said distance “a” as “P”, and setting an interval between said two supporting areas along a tangent line of said rotating body passing through said contact point “P” as a distance “A”, said supporting section is formed so as to meet a relation of “A”>“a”.
