PROBLEM TO BE SOLVED: To provide a lubricant supply device capable of reliably detecting that a remaining amount of solid lubricant is reduced to a predetermined amount or less, an image forming apparatus, and a process cartridge.SOLUTION: A lubricant supply device includes: an opening 31e for detection on a storage case 3e; a contact protrusion 31d that penetrates through the opening 31e for detection and protrudes to the outside of the storage case 3e, and moves in association with a movement of a protruding solid lubricant 3b while being scraped off by an application roller 3a; and a remaining amount detection unit 40 that is arranged outside the storage case 3e, and detects that the contact protrusion 31d reaches a predetermined position so as to detect that a remaining amount of the solid lubricant 3b is reduced to a predetermined amount or less. A position of the opening 31e for detection is set to be close to a center part by a predetermined distance or more from an end in a longitudinal direction of the solid lubricant. |
