Sheet stripping members for fixing device for fixing images of an original document on sheets of copy materials

A copy sheet stripping device within an instrument for fixing images of an original document on a copy material by using a pair of rollers in pressure engagement, comprising:

• first means for detecting the approach of the copy material toward said pair of rollers and providing a first detection signal in response to the approach;
• second means for sensing the exit of the copy material from said pair of rollers and providing a second detection signal in response thereto;
• copy sheet stripping means for stripping the copy material from one of said pair of rollers;
• and
• energization means which is activated by the first detection signal to move the copy sheet stripping member into engagement with that roller and, subsequently activated by the second detection signal to move the copy sheet stripping member away from that roller.

A device for separating sheets from a moving member having a width transverse to the direction of travel, comprising:

• stripping means for separating said sheet from said moving member, said stripping means being rigid and having an edge capable of engaging the moving member;
• means for sensing when said sheet is in close proximity to said stripping means;
• and
• means responsive to said sensing means for moving said stripping means into engagement with said moving member only when said sheet is detected by said sensing means.
