Claims

[Scope of utility model registration request]

In a device that has a pair of fixing rollers and a pressure roller for fixing the toner image on the transfer paper, and a separating claw pressed against the fixing roller for separating the transfer paper from the fixing roller, a pin is inserted into the support shaft. The recessed part of the separation claw is pressed against the pin by a spring, so that the direction in which the separation claw contacts the fixing roller and the tangential direction of both rollers diverge in the transfer paper advancing direction at a predetermined angle, and the separation claw guide surface is A separating claw device in an edge-shaped fixing device.
