A lubricant applicator includes a block of lubricant, a supply member contactable against the block of lubricant to scrape the block of lubricant, and a lubricant gauge to detect whether a remaining amount of lubricant is less than a threshold value. The lubricant gauge includes a rotary member rotatable about a pivot, a pressing member disposed opposite the rotary member to rotate the rotary member by pressing a contact part of the rotary member as the block of lubricant is consumed, and a detection part of the rotary member opposite to the contact part across the pivot of the rotary member. A length of the rotary member from the pivot to the detection part is longer than a length of the rotary member from the pivot to the contact part. |
