An image forming apparatus includes a media roll, art image forming device, and a feeder. In the media roll, a printing medium having an adhesive face is wound in a roll shape. The image forming device forms an image on the printing medium. The feeder feeds the printing medium. The feeder includes a protection belt and a pair of rotary bodies. The protection belt presses against and protects the adhesive face of the printing medium. The pair of rotary bodies sandwich and press the printing medium and the protection belt between the pair of rotary bodies. An approach angle of the printing medium is within a range from 0° to 30° and is formed by the printing medium drawn from the media roll and approaching to between the pair of rotary bodies and an opposing face of the protection belt opposing the image forming device.

A taper coupling structure includes a groove, serving as a hollowed part, provided in a rear end surface of a hub. The groove is formed continuously in the circumferential direction and uniformly in the radial direction. In the state in which a taper shaft is fitted in the hub, the groove interferes with the taper shaft in the radial direction. An inner shell part, which is a portion on the inside of the groove in the radial direction, has a low radial rigidity because of the presence of the groove. For this reason, if a force is applied from the hollow portion of a flange part toward the outside in the radial direction, the diameter of the inner shell part is liable to be increased in the radial direction by elastic displacement (deflection).

A power switching apparatus includes: a pressure tank having tube-like openings in a shank portion and having an insulating gas sealed therein; a vacuum valve housed in the pressure tank and connected to the pressure tank at one end; bushing conductors penetrating through the openings of the pressure tank and electrically connected to the vacuum valve; and current transformers provided on an outside of the pressure tank and measuring a current flowing through the bushing conductors. Tube-like current transformer installation portions on which to install the current transformers are provided above the openings of the pressure tank and an outside diameter of the openings of the pressure tank is made larger than an outside diameter of the current transformer installation portions.

Full-mesh WDM transmission units, each of which includes n number of interfaces and is capable of establishing a bidirectional full-mesh communication between all of the interfaces using wavelength paths based on a wavelength division multiplexing technique, are connected in a multistage tree-shaped structure by internetwork connection units through edge-packet transfer units connected to the respective interfaces. Therefore, it is possible to hold a direct communication between user terminals connected to the edge-packet transfer units of the same full-mesh WDM transmission unit, and to realize scalability by a multistage connection configuration.

A developing device includes a rotator that rotates around a shaft, and a bearing element that supports the shaft to a housing. A sliding element formed of a composite material that contains self-lubricating thermoplastic olefin resin as a base material is used as the bearing element. The sliding element formed of the composite material has at least a ratio of numerical values of “Rockwell hardness”/“bending elastic modulus” in a range from 25 to 45, and provides a sliding surface of which a frictional coefficient is lower than that of the sliding element formed of the base material.

An image forming apparatus is disclosed. The image forming apparatus includes a toner supplying device, a toner container, and a developing device. The toner supplying device supplies toners stored in the toner container to the developing device. The toner supplying device includes a toner tank which stores toners discharged from the toner container, a toner carrying section which carries the toners stored in the toner tank in an obliquely upward direction, and a toner dropping route which causes the toners carried by the toner carrying section to drop into the developing device by toner own weight. The toner carrying section controls an amount of the toners to flow into the toner dropping route.
