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.
摘要翻译：用于显影静电图像的调色剂包括粘合剂树脂和着色剂，其中粘合剂树脂包括具有酸酐基的乙烯基共聚物，并且粘合剂树脂的总酸值（A）为2-100mgKOH / g，和归因于酸酐基团的总酸值（B）低于6mgKOH / g，使得[（B）/（A）]×100为60％以下。由于粘合剂树脂具有部分归因于酸酐基团的特定酸值，因此调色剂在带电性和放电性之间具有足够的平衡，使得调色剂在各种环境条件下显示出稳定的性能。调色剂特别有利地构成为适用于不对称交流偏压电场的细粒度的磁性调色剂。

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.

The toner has a binder resin and at least one of a magnetic powder and a colorant. The toner has a weight average particle diameter (D.sub.4) of from 4 .mu.m to 11 .mu.m; a coefficient A of variation of number-base distribution, of not more than 40, which is a coefficient represented by the formula: A=S.sub.n /D.sub.1 .times.100 wherein S.sub.n represents a standard deviation of number-base distribution, and D.sub.1 represents a length average particle diameter (.mu.m) on the basis of number; and a coefficient B of variation of volume-base distribution, of not more than 30, which is a coefficient represented by the formula: B=S.sub.W /D.sub.4 .times.100 wherein S.sub.W represents a standard deviation of volume-base distribution, and D.sub.4 represents a weight average particle diameter (.mu.m) on the basis of weight.
