表面で全反射することに原因している。This means that the cleaning blade is wear resistant,
Generally, the cleaning blade is made of urethane rubber because it requires chemical stability, corona resistance stability, environmental stability, and reliable cleaning performance. This is due to the fact that the pre-exposure is totally reflected on the surface of the cleaning blade because it is finished to a near-mirror finish due to conditions such as the precision of the edges.
