摘要:
A toner, such as an electrostatic latent image developing toner and a MICR toner, has an even charge distribution, and exhibits balanced charging characteristics without decreases in frictional electrification or increases in charge, as well as superior fluidity, environmental independence, and durability. This is achieved by treating toner particles, which include binder resin and magnetic particles, with an external additive particle that is one of: a combination of rutile-type titanium oxide and anatase-type titanium oxide; and rutile-type titanium oxide that falls in a range of 5 to 10% by volume when a total volume of the toner is regarded as being 100%.

The present invention uses a single substrate to provide a small-size optical waveguide element that requires no optical axis adjustments, can be driven at a low voltage, is excellent in light utilization efficiency, and can rapidly two-dimensionally deflect a light beam. A right-triangle upper electrode and a rectangular transparent upper electrode are formed on top of a thin-film optical waveguide formed on a conductive substrate to serve as a lower electrode, and an emission right-angled prism is secured on top of the transparent upper electrode. A voltage is applied between the upper electrode and the conductive substrate, and between the transparent upper electrode and the conductive substrate. A horizontal deflection is performed upon application of a voltage to the upper electrode and a vertical deflection is performed upon application of a voltage to the transparent upper electrode.
