Title: Relase agent coating roller
Inventor: YAMADA TAKASHI
IPC: G03G15/20
Filed: 2000-07-03
Abstract: PROBLEM TO BE SOLVED: To reduce leakage while holding a large amount of a release agent by improving the contradicting relation between the release agent holding amount and release agent holding force of a release agent coating roller using a ceramic porous body and then embodies the small size, long life, and high reliability of a release agent coating roller. SOLUTION: The distribution density of pores 55 of the ceramic porous body of a release agent holding layer 35 is equal for the outer and inner peripheral sides on the average, but the mean diameter (d) is different. Consequently, the release agent holding amount increases on the inner peripheral side where there is no adverse effect on the leakage and decreases toward the outer peripheral side so that the leakage is prevented on the outer peripheral side.
