摘要：
To provide an image forming apparatus in which variations in the contact pressure produced between a photosensitive drum and a developing roller is suppressed, whereby image quality can be improved. A development unit and a drum unit are rotatably connected to each other with a link member interposed therebetween. Gears for transmitting a driving force are supported at two rotation support points of the link member, whereby the driving force is transmitted to the development unit.
