摘要： A method of preparing a toner includes: adding a first external additive having an average primary particle diameter of between about 30 nm and 200 nm to toner particles including a binder resin and a colorant and stirring the first external additive with the toner particles to form a first external additive layer on the surfaces of the toner particles; and adding a second external additive having an average primary particle diameter between about 5 nm and 30 nm to the toner particles having the first external additive layer and stirring the second external additive with the toner particles to form second external additive layers on the first external additive layers. A stirring line speed of the first external additive is less than a stirring line speed of the second external additive. The method of preparing a toner increases the endurance of the toner and prevents a developing member from being contaminated. External additives having different average primary particle diameters are sequentially added to toner particles including a binder resin and a colorant so that external additives having greater average primary particle diameters are uniformly coated on the surface of the toner particles. Accordingly, a uniform charge and the fluidity of the toner are improved and contamination of a charge roller and other developing members due to a separation of the external additives is prevented.

摘要： An improved label stamper which is capable of stamping prices on labels attached on a tape so as to attach the stamped labels on commodities is disclosed. A tape loading mechanism of the label stamper is constituted such that a loading case goes in and out of the machine by functions of a pair of folding and extending legs, so that the label tape can be loaded in a convenient manner. A guide is constituted such that a front plate and a rear plate are fastened across a narrow gap, and this gap forms a guide channel. In a holding mechanism, a push plate is disposed facing toward a base plate, and the push plate interlocks a movable lever to the loading case. Thus, if the tape is inserted into the guide channel, the tape is automatically press-held to the base plate. In a stamping mechanism, a selecting hole of a selecting wheel for driving a stamping belt is provided with a recess and a triangular protuberance. Thus two selecting wheels will never be engaged together, and fingers of a selecting bar are accurately coupled to the selected wheel. In a carrying mechanism, carrying rollers are provided in the form of a cartridge, and this cartridge is replaceably accommodated within a cartridge compartment. This improves the compactness and the performance of the label stamper, and the cartridge can be conveniently replaced.
摘要翻译：公开了一种改进的标签压模，其能够对附着在带上的标签上的价格进行冲压，以将冲压标签附着在商品上。标签压模的带装载机构构成为使得装载箱通过一对折叠和延伸的腿的功能进出机器，从而可以以便利的方式装载标签带。引导件被构造成使得前板和后板紧固在窄间隙上，并且该间隙形成引导通道。在保持机构中，推板朝向基板配置，推板将可动杆联结于装载箱。因此，如果带被插入引导通道中，则带被自动地按压到基板。在冲压机构中，用于驱动冲压带的选择轮的选择孔设置有凹部和三角形突起。因此，两个选择轮将永远不会啮合在一起，并且选择杆的手指精确地联接到所选择的轮。在承载机构中，承载辊以盒的形式提供，并且该盒更换地容纳在盒仓内。这提高了标签压模的紧凑性和性能，并且可以方便地更换盒。
