Abstract:
1. A lubricant supplying device comprising: a solid lubricant; a supplying member that comes into contact with the solid lubricant and supplies a lubricant scraped off by rubbing the solid lubricant to a target to be supplied with the lubricant; a residual amount detecting unit that detects that a residual amount of the solid lubricant is equal to or smaller than a predetermined amount by detecting that the length of the solid lubricant in a direction in which the solid lubricant moves while being scraped by the supplying member is equal to or smaller than a predetermined value; and a lubricant end determining unit that determines that the solid lubricant is in an end state when the amount of a lubricant supplying operation reaches a threshold after the residual amount detecting unit detects that the residual amount of the solid lubricant is equal to or smaller than the predetermined amount, wherein the lubricant end determining unit makes a threshold of the amount of the lubricant supplying operation at temperature or humidity of equal to or lower than a predetermined value lower than a threshold of the amount of the lubricant supplying operation at temperature or humidity of higher than the predetermined value.
