摘要： There is provided a mobile terminal with an international dialing operation function, which enables unfamiliar and troublesome conversion into an international telephone number to be performed with a simpler operation and which performs conversion into an appropriate telephone number according to the location where the terminal has moved. The mobile terminal identifies its location with a location identification section and determines whether an originating call is a call to the originator's country or to a foreign country according to the identified location. If the call is to a foreign country, an international prefix according to the identified location is identified. Furthermore, a country code is set to correspond to the originator's country, or it is identified from the inputted counterpart's telephone number and the like. Conversion into an international telephone number is performed using the country code, and then a call is originated. When the call is originated to the originator's country, the domestic telephone number is used for origination without being converted. A converted number is displayed on an operation screen so that the originator may confirm whether it is appropriate or not.

摘要： A toner for developing electrostatic images, comprises a binder resin and a colorant, wherein the binder resin comprises a vinyl copolymer having an acid anhydride group, and the binder resin has a total acid value (A) of 2-100 mgKOH/g and a total acid value (B) attributable to acid anhydride group of below 6 mgKOH/g so that [(B)/(A)].times.100 is 60% or less. Because the binder resin has a specified acid value partly attributable to acid anhydride group, the toner is provided with an adequate balance between chargeability and dischargeability, so that the toner shows a stable performance under various environmental conditions. The toner is particularly advantageously constituted as a magnetic toner of fine particle sizes suitably used under application of unsymmetrical alternating bias electric field.

摘要： An image forming apparatus is formed by providing a latent image-bearing member for holding an electrostatic image thereon and a toner-carrying member for carrying a prescribed magnetic toner comprising a binder resin and magnetic powder and having a particle size distribution including 12% by number or more of magnetic toner particles of 5 microns or smaller, 33% by number or less of magnetic toner particles of 8-12.7 microns and 2% by volume or less of magnetic toner parcitles of 16 microns or larger so as to provide a volume-average particle size of 4-10 microns. At the developing station, an alternating bias voltage comprising a DC voltage and an unsymmetrical AC voltage in superposition is applied between the toner-carrying member and the latent image-bearing member to provide an alternating bias electric field comprising a development-side voltage component and a reverse-development side voltage component. The development-side voltage component has a magnitude equal to or larger than that of the reverse development-side voltage component and a duration smaller than that of the reverse-development side voltage component, so that the magnetic toner on the toner-carrying member, particularly fine powdery fraction thereof effective for high-quality development, is effectively transferred to the latent image-bearing member to develop the electrostatic image thereon at the developing station.

摘要： A monocomponent-type developer for developing electrostatic images, includes a magnetic toner containing at least a binder resin and magnetic powder, and 0.5-10 wt. % (based on the magnetic toner) of inorganic fine powder having a length-average particle size of 0.1-5 .mu.m. The developer has a number-basis particle size distribution such that particles of 4 .mu.m or smaller are contained at 5-18% by number and particles of 4-10 .mu.m are contained at at least 60% by number. The developer has a volume basis particle size distribution such that particles of 12.7 .mu.m or larger are contained at at most 10% by volume. The developer has a weight-average particle size of 7-11 .mu.m. The developer is particularly useful for development under application of a DC-superposed asymmetric AC bias electric field including a development-side voltage component with a larger magnitude and a shorter duration than a reverse development-side voltage component.
