ABSTRACT:
An image forming apparatus that includes: a process unit; a driving source; a first driving unit that rotates when a rotation driving force generated by the driving source is transmitted; and a connection switching unit that switches between a transmission state in which the rotation driving force is transmitted to the first driving unit and a non-transmission state. The process unit includes: a transmission permission unit that switches a state of the connection switching unit into the transmission state, when the process unit exists at a process mounting location with respect to the image forming apparatus; and a second driving unit that joints with the first driving unit when the process unit exists at the process mounting location and rotates a rotation driving subject in the process unit by a rotation force of the first driving unit.
