Patent ID: 8750749

Claim:
An image forming apparatus comprising: a rotatable member-to-be-cleaned having elasticity; a cleaning member, having elasticity, for removing a deposited matter deposited on said member-to-be-cleaned; and a supporting portion for supporting said cleaning member so that said cleaning member swings around a swing fulcrum, wherein an upstreammost sliding contact point is a most upstream point, with respect to a movement direction of said member-to-be-cleaned, along a sliding contact portion where said cleaning member and said member-to-be-cleaned slide-contact each other, wherein a tangential line where said cleaning member and said member-to-be-cleaned are in contact with each other during movement of said member-to-be-cleaned is a rectilinear line passing through the upstreammost sliding contact point, wherein the swing fulcrum is located downstream of the upstreammost sliding contact point with respect to the movement direction, and wherein, in a region downstream of the upstreammost sliding contact point with respect to the movement direction, a rectilinear line passing through the upstreammost sliding contact point and through the swing fulcrum is located closer to said member-to-be-cleaned than the tangential line where said cleaning member and said member-to-be-cleaned are in contact with each other.
