ELECTROSTATIC PROCESS COPIER, SPRING PRESSING BLADE DEVICE, AND SPRING PRESSING BLADE MEMBER

摘要

PROBLEM TO BE SOLVED: To provide a spring pressurization blade device having multiple layers and giving reduced stress and creep ratio when it is bent in pressurization application. SOLUTION: A spring pressing device 80 is provided with a guide member 84 supporting a blade member 90, and the guide member 84 is provided with a curve portion 86 supporting the blade member 90 bent by pressing. The spring pressing device 80 is also provided with the first edge connected to the guide member 84 and the second edge bent to the curve portion 86 of the guide member 84 by pressing on the opposite side. The blade member 90 is composed of multiple blade layers L1, L2 to reduce the creep ratio and stress of the blade member 90 at the time of pressing. Multiple blade layers L1, L2 are connected to each other at the first edge, and they are made freely slidable at the second edge.
