    • An apparatus is disclosed for detecting defects on a sample inspected by different inspection apparatuses. A data processing unit receives position information of a first defects group in a first coordinate system, based on inspection of the sample under a first condition using a first defect inspection apparatus. The data processing unit receives position information of a second defects group in a second coordinate system, after least one processing step has been performed on the sample. Position information of the second defects group is obtained by inspecting the sample under a second condition using a second defect inspection apparatus which is different from the first defect inspection apparatus. A position correction unit corrects error of relative position information on the first defects group and the second defects group, and the first and second defects groups are checked.
    • 公开了一种用于检测由不同检查装置检查的样品上的缺陷的装置。 数据处理单元使用第一缺陷检查装置,基于第一条件下的样本检查,接收第一坐标系中的第一缺陷组的位置信息。 在对样本进行了至少一个处理步骤之后,数据处理单元接收第二坐标系中的第二缺陷组的位置信息。 使用与第一缺陷检查装置不同的第二缺陷检查装置,在第二条件下检查样品,获得第二缺陷组的位置信息。 位置校正单元校正第一缺陷组和第二缺陷组的相对位置信息的误差,并且检查第一和第二缺陷组。

    • In an image forming apparatus adopting a cleanerless process, there is provided a technique of preventing deterioration of picture quality due to photoreceptor filming or color mixture. An image forming apparatus of a cleanerless process in which a toner image is formed on an image bearing body by a developing unit, and a toner remaining on the image bearing body is collected by the developing unit, includes an intermediate transfer belt made of laminated layers of plural conductive materials different from each other and having a belt surface onto which the toner image is transferred from the image bearing body at a specified transfer position, and a transfer unit configured to press the intermediate transfer belt to the image bearing body at the specified transfer position and to apply a specified bias voltage to the intermediate transfer belt, wherein with respect to the plural conductive materials of the intermediate transfer belt, a layer closer to a side of either one of the toner transferred from the image bearing body and the transfer unit, where negative polarity is set, has a higher volume resistance value.
    • 在采用无清洁剂处理的图像形成装置中,提供了防止由于感光体成膜或混色引起的图像质量劣化的技术。 一种无清洁器工艺的图像形成装置,其中通过显影单元在图像承载体上形成调色剂图像,并且由显影单元收集残留在图像承载体上的调色剂图像,包括由层压层制成的中间转印带 多个导电材料彼此不同,并且具有带表面,调色剂图像在图像承载体上以指定的转印位置转印到该带表面上;以及转印单元,其被配置为在指定的转印位置将中间转印带按图像承载体 转印位置,并向中间转印带施加指定的偏置电压,其中相对于中间转印带的多个导电材料,更靠近从图像承载体转印的调色剂中的任一个的一侧的层和转印 设置负极性的单位具有较高的体积电阻值。
