Abstract
The photosensitive drum unit of an image forming apparatus is selectively coupled to the upper cover. The user can elect to have the drum unit pivot up with the upper cover or stay in the main housing independently of movement of the upper cover. The same operation that controls whether the drum unit moves with the upper cover can control whether a kit holder stays in place in the main housing or pivots up to make it easier to change kit components such as a toner container.
