PROBLEM TO BE SOLVED: To provide an image formation device capable of enhancing a probability that teeth of a cone clutch are sufficiently engaged with each other.SOLUTION: In an image formation device driving an image carrier through a drive transmission member from a drive motor, drive force is transmitted between a motor shaft 81a of the drive transmission member and a drum shaft 2a of the image carrier through a cone clutch 7 with teeth. Then, the number of teeth 711, 711, 711 of a first coupling 71 of the cone clutch 7 is less than the number of teeth 721, ... of a second coupling 72, and is an odd number. |
