To provide a transmission/coupling device simple in structure and capable of carrying out uniform velocity transmission and quick coupling/decoupling of shafts. A shaft 101 of a photo-sensitive drum 23 has a taper section 103 and a first coupling member 105, mounted on the shaft 101, having a projection 107. An output shaft 111 of a drive motor 67 has a second coupling member 113, mounted on the shaft 111, having a cylindrical bore 115 and a projection 119. When the shafts 101 and 111 are coupled to each other, the taper section 103 is in line-contact with the cylindrical bore 115 to define an engagement circle, and the projections 107 and 119 are engaged with each other to define a power transmission point P which exists in a bisector plane A including the engagement circle, whereby uniform velocity transmission is realized.
