An image forming and cutting apparatus has an inkjet head with a first coupling member having a hole, a cutting head with a second coupling member having a hole, and a coupling pin that is received by the holes of the coupling members to couple the first and second coupling members to each other. The coupling pin has first and tapered portions with a columnar portion interposed therebetween. The hole of the first coupling member has a tapered surface for receiving the first tapered portion, and the hole of the second coupling member has a tapered surface portion and a columnar surface portion for receiving the second tapered portion and the columnar portion, respectively. The first coupling member is made of an elastic material and is configured to be pressed and deflected by the coupling pin due to elasticity of the elastic material when the coupling pin is moved in the first direction and is received by the holes of the first and second coupling members so that the first and second coupling members are coupled to one another with a gap therebetween while the columnar portion of the coupling pin protrudes from the hole of the second coupling member.
