In a reproduction apparatus including a fusing assembly for fixing a marking particle developed image to a receiver member, wherein a release liquid is applied to the fusing assembly to prevent marking particles of such image from adhering thereto, a mechanism for cleaning the assembly. The cleaning mechanism includes a blade member having an elongated body with an edge surface adapted to be located in scraping engagement with a portion of the fusing assembly. A housing assembly is provided for retaining the blade member, the end portions of the elongated body of the blade member extending further from the housing assembly than the central portion of the elongated body of the blade member by at least one spacer. The housing assembly is supported relative to the fusing assembly such that substantially the entire edge surface of the body of the blade member contacts the portion of the fusing assembly, with the end portions oriented to direct release liquid toward the central portion of the blade member elongated body.
