Abstract
A seal member is described that is configured to prevent leakage of micro-powder from a rotating body such as a developing roller. The seal member of the rotating body of an image forming device using toner of the micro-powder includes base fabric consisting of knitting or fabric, loop-shaped pile yarn or cut-shaped pile yarn, which is supported on a surface of the base fabric by the entanglement or support of ground yarn of the base fabric, and a coating layer which has penetrated from a back surface of the base fabric to which a coating agent is applied to the side of pile yarn. A height of the coating agent which has penetrated from the back surface of the base fabric is the same as or less than a thickness of the base fabric which is configured by the height of the ground yarn which supports the pile yarn.
