Abstract
An image forming apparatus prevents link members for monochrome and for color from coming off while suppressing an increase in rotatory torque and a deficiency of clutch capacity for transmitting a driving force to a cam shaft. Coming-off protection sections for preventing the coming off of a second link member which is the link member for color is provided in a cam section for monochrome. In other words, it is not necessary to provide a coming-off protection section in a second cam section which is a cam section for color requiring a large rotatory torque. This eliminates the need for a coming-off protection section of the cam section for color to act on the link member for color when a cam is turned by a driving source.
