    • This invention relates to a toner for development of electrostatic images to be used for development of electrostatic images formed in electrophotography, electrostatic printing, electrostatic recording, etc., and an image forming method by use thereof.The toner of the present invention uses a resin constituted mainly of a copolymer comprising a crystalline polymer block and an amorphous polymer block chemically bound together, the cyrstalline polymer block has a specific melting point, the amorphous polymer block has a specific glass transition point, the moduli of the toner has a value with a specific range, and therefore according to the present invention, a toner excellent in durability can be provided, which is capable of fixing sufficiently even at a low temperature and yet also good in off-set resistance within such a temperature range, further having excellent anti-blocking characteristic, flowability, charging characteristic, anti-filming characteristic, cleaning property, thus being capable of forming good visible images stably.
    • 本发明涉及用于显影电子照相,静电印刷,静电记录等静电图像的静电图像显影用调色剂及其使用的图像形成方法。 本发明的调色剂使用主要由包含结晶聚合物嵌段和化学键合在一起的无定形聚合物嵌段的共聚物构成的树脂,所述硅橡胶聚合物嵌段具有特定的熔点,所述无定形聚合物嵌段具有特定的玻璃化转变点, 调色剂的模量具有特定范围的值,因此根据本发明,可以提供耐久性优异的调色剂,即使在低温下也能够充分固化,并且还具有良好的抗偏置性 这样的温度范围,进一步具有优异的防粘连性,流动性,充电特性,抗成膜特性,清洁性,从而能够稳定地形成良好的可见光。

    • An image forming apparatus includes: a tray on which documents are stacked; a first document size detector for detecting a size of the documents stacked on the tray; a second document size detector for detecting a size of each of the documents conveyed from the tray; an automatic document feeding device having a document reading section for reading an image of each of the documents; an image forming section including a transfer material feeder for feeding transfer materials; and a controller for selecting and feeding transfer materials according to the detected document size. When the first document size detector detects that the size of the documents is identical to a regular size, the controller selects and feeds the transfer materials in accordance with the regular size, and when the first document size detector detects that the size of the documents is not identical to the regular size, the controller controls the second document size detector to detect the size of each of the documents conveyed from the tray, and selects and feeds transfer materials in accordance with the size detected by the second document size detector.
    • 一种图像形成装置,包括:堆叠文件的托盘; 用于检测堆叠在托盘上的文件尺寸的第一文件尺寸检测器; 第二文件尺寸检测器,用于检测从托盘传送的每个文件的尺寸; 一种自动文件馈送装置,具有用于读取每个文档的图像的文档读取部分; 图像形成部分,包括用于馈送转印材料的转印材料馈送器; 以及用于根据检测到的文档尺寸选择和馈送转印材料的控制器。 当第一原稿尺寸检测器检测到文档的尺寸与常规尺寸相同时,控制器根据常规尺寸选择并馈送转印材料,并且当第一文档尺寸检测器检测到文档的尺寸为 与常规尺寸不同的是,控制器控制第二文件尺寸检测器以检测从托盘传送的每个文件的尺寸,并根据第二文档尺寸检测器检测到的尺寸来选择和馈送传送材料。
