Support ski for film cleaning device

A support apparatus for a recording medium in the form of an endless belt extended between at least a pair of rollers, said medium having a recording surface on which a developed image is formed and a back surface opposite said recording surface, said support apparatus comprising:

• a non-rotating ski defining a supporting surface which faces and slidingly engages the back surface of said recording medium,
• a flexible member on which the ski is mounted,
• a biasing means for urging the ski toward the recording medium, to urge the supporting surface by itself and with the flexible member against the back surface of the recording medium, and
• means associated with said ski for adjusting the position of the ski with respect to the back surface of the recording medium, such adjusting means including means for fixing the flexible member to a first end of the ski and means for coupling a second end of the ski to the flexible member which means for coupling permits relative movement between the ski and the flexible member toward and away from the recording medium.

Apparatus for cleaning a recording medium in the form of an endless belt extended between at least a pair of rollers, having a recording surface on which a developed image comprised of particles is formed and a back surface opposite said recording surface, the cleaning apparatus comprising:

• magnetic brush means for removing residual particles on the recording surface, said means for removing being disposed on the recording surface side of said recording medium;
• supporting means for supporting the back surface of the recording medium and for biasing the recording surface toward said magnetic brush means for removing residual particles, said supporting means including:
• a support member mounted downstream of the magnetic brush means and having a supporting surface which faces the back surface of said recording medium,
• a flexible member on which the support member is mounted, and
• a biasing means for urging the support member, by itself and with the flexible member, toward the magnetic brush means for removing to urge the supporting surface against the back surface of the recording medium.
