PROBLEM TO BE SOLVED: To provide a lubricant supply device configured to reliably detect that the amount of remaining solid lubricant has decreased to a predetermined amount or less, an image forming device and a process cartridge.SOLUTION: A remaining amount detection part 40 for detecting that the amount of remaining solid lubricant 3b has decreased to a predetermined amount or less includes: a first electrode member 42a; a second electrode member 42b arranged opposite the first electrode member 42a, and directly or indirectly pushed by a lubricant holding member 3d to at least partially move toward the first electrode member, and coming in contact with the first electrode member 42a when the amount of remaining solid lubricant 3b has reached the predetermined amount; and a resistance detection part 42c that applies a voltage between the first and second electrode members 42a, 42b to detect whether they are electrically connected or not. At least a contact surface of the first electrode member 42a in contact with the second electrode member 42b and a contact surface of the second electrode member 42b in contact with the first electrode member 42a are disposed in parallel to a vertical direction. |
