Lubricant supplying method, supporting member and rotatable member unit

摘要

A lubricant supplying method for supplying a lubricant to a sliding portion between a cylindrical rotatable member for use in an electrophotographic image forming apparatus and a supporting member for slidably supporting an inner peripheral surface at one end side of the rotatable member with respect to a rotational axis direction of the rotatable member, includes a step of engaging the supporting member, including a hollow portion and an opening which communicates with the hollow portion and is provided at a position in which the opening opposes the sliding portion, with the rotatable member at the one end side; and a step of supplying the lubricant from the hollow portion toward the sliding portion through the opening.

主权项

1. A supporting member for slidably supporting an inner peripheral surface at one end side of a cylindrical rotatable member for use in an electrophotographic image forming apparatus with respect to an axial direction of the rotatable member, said supporting member comprising:
a first opening, provided at a position in which said first opening opposes the inner peripheral surface of the rotatable member; a hollow portion which communicates with said first opening; and a second opening which is provided at a position in which said second opening is opened toward an outside of the rotatable member and which communicates with said hollow portion so that a lubricant is capable of being supplied to a sliding portion between the rotatable member and said supporting member from outside of said supporting member via said hollow portion and said first opening.
