The lower housing has a supporting-guiding device mounted pivotably between an elevated position and a lowered position, a holding device pivotably mounted between a holding position at which the supporting-guiding device is held at the elevated position and a release position at which the supporting-guiding device is permitted to move to the lowered position, and a biasing position for elastically biasing the holding device at the holding position. The process unit has a first unit and a second unit. The supporting-guiding device positioned at the elevated position can be mounted on and detached from the first unit. The second unit is separably combined with the first unit. The first unit includes a developing device, and the second unit includes a rotating drum having a photosensitive member disposed on the surface.
