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 remaining amount detection unit 40 detecting that a remaining amount of solid lubricant 3b is reduced to a predetermined amount or less is configured to rotate under its own weight, and includes: a rotation member 41 that comes into contact with the solid lubricant 3b or a lubricant holding member 3d so as to regulate its rotation by a rotation force, from an initial stage of use of the solid lubricant 3b to when the remaining amount of the solid lubricant 3b is reduced to the predetermined amount; and a rotation detection unit 42 that detects a position different from a contact position where the rotation member 41 comes into contact with the solid lubricant 3b or the lubricant holding member 3d so as to detect the rotation of the rotation member 41. |
