An image forming apparatus includes a plurality of image forming units, a transfer belt that receives toner images from the plurality of image forming units, and a plurality of transfer rollers for rotating the transfer belt in an image forming direction. The image forming apparatus also includes a tensioner having a first end and a second end, and a tension roller coupled to the first end. The tension roller is in contact with the surface of the transfer belt. The tensioner is rotatable at a second end positioned away from a surface of the transfer belt.

An image forming apparatus is provided including a toner supply receiver and an image formation unit configured to form an image on an image-transferring member using toner from the toner supply receiver. The toner supply receiver preferably has an opening configured to receive a toner bottle, and a base portion having a receiver coupling configured to releasably retain the toner bottle. The base portion further includes an inner wall including an insertion guide surface configured to cause rotation of the toner bottle relative to the base portion as the toner bottle is inserted into the toner supply receiver to thereby align the toner bottle with the receiver coupling in a predetermined manner.

An exposure device has a plurality of light emitting units for emitting laser beams based on image signals. These laser beams emitted from the respective light emitting units are combined through respective galvanomirrors and half mirrors and conducted through a cylindrical lens to a polygon mirror. The respective combined beams reflected on the polygon mirror are illuminated onto an exposure light position on the surface of a photosensitive drum through two f&thgr; lenses and a mirror. At this time, through the rotation of the polygon mirror, the respective laser beams are deflected in a main scanning direction and, through the rotation of the photosensitive drum, they are deflected in a sub-scanning direction to allow the surface of the photosensitive drum to be scanned with the exposure beams. At a position downstream of the cylindrical lens along a light path of the respective laser beams but upstream of the polygon mirror, a stop is so provided as to allow the combined beams to be passed and the cross-sectional configuration of the combined beams to be shaped. The stop shapes the cross-sectional configuration of the respective laser beams in the main scanning direction only.

According to one embodiment, an inkjet recording apparatus includes a plurality of inkjet heads, a common supply pipe, a common collection pipe and an ink tank device. The common supply pipe includes an upper inner wall from one end side in a longitudinal direction to the other end side, which is inclined with respect to a horizontal direction from the one end side to the other end side if an ink flow direction and opposite direction of a gravitational force are defines as positive axes. The common collection pipe is supplied with the ink from the common supply pipe at one end side in the longitudinal direction. The ink tank device supplies the ink to the one end side of the common supply pipe, and collects the ink from the common collection pipe.
