    • A developing device having a developing sleeve loosely mounted on the peripheral surface of a cylindrical developing roller. Both end portions of the developing sleeve are pressed against the developing roller by a pair of guide pads so that a part of the developing sleeve keeps contacting the developing roller. The force applied by the the pair of the guide pads to the developing sleeve is in such an extent that driving force of the developing roller is transmitted to the developing sleeve in the portion in which the developing sleeve contacts the developing roller and that the developing sleeve is allowed to rotate in correspondence with the rotation of the developing roller. A blade member for forming a thin layer of toner on the developing sleeve is in contact with the peripheral surface of the developing sleeve. Fine irregularities are formed on the peripheral surface of the developing sleeve so as to hold toners adhered thereto. Compared with a developing sleeve having no irregularities, fine irregularities formed on the inner peripheral surface of the developing sleeve increases frictional force in the portion in which the developing sleeve contacts the developing roller. Fine irregularities are formed on both the peripheral and inner peripheral surface of the developing sleeve by an electroforming using a mother roller having irregularities on the peripheral surface thereof.
    • 一种显影装置,其具有松散地安装在圆柱形显影辊的圆周表面上的显影套筒。 显影套筒的两个端部通过一对引导垫压靠在显影辊上,使得显影套筒的一部分保持与显影辊接触。 由一对引导垫施加到显影套筒上的力的程度使得显影辊的驱动力在显影套筒与显影辊接触的部分中传递到显影套筒,显影套筒 允许与显影辊的旋转对应地旋转。 用于在显影套筒上形成薄层调色剂的刀片构件与显影套筒的外围表面接触。 在显影套筒的周面上形成细小的凹凸,以便保持附着在其上的调色剂。 与没有凹凸的显影套筒相比,形成在显影套筒的内周面上的微细凹凸增大了显影套筒与显影辊接触的部分的摩擦力。 通过使用在其外周表面上具有凹凸的母辊的电铸,在显影套筒的外周面和内周面上形成微细凹凸。

    • A memory management method is provided to manage a memory in which areas of a garbage collected Java heap memory and a non-garbage collected external heap memory can be secured, by using a program executed by a processor in a computer. If it is judged that there is no reference to all data arranged in the external heap memory or starting point data of reference relations included in the all data, from data arranged outside the external heap memory, then the external heap memory is judged to be capable of being deallocated. As a result, it becomes possible to implement memory management in which garbage collection needing a long time program stop is not conducted and an additional API is not used.
    • 提供了一种存储器管理方法,用于通过使用由计算机中的处理器执行的程序来管理可以确保垃圾收集的Java堆存储器和非垃圾收集的外部堆存储器的区域的存储器。 如果判断不存在外部堆存储器中排列的所有数据或包含在全部数据中的参考关系的起始点数据,则从外部堆存储器外部的数据中判断外部堆存储器是否能够 被释放。 结果,可以实现不进行需要长时间程序停止的垃圾回收和不使用附加API的存储器管理。

    • A computer includes a storage region in which an object generated by executing a program is disposed, and a control unit that performs execution of the program and releasing of the storage region. The control unit updates time information using garbage collection, a capacity of objects in a memory, or similar as a trigger, acquires information of a program generating an object and time information at the time of generation of the object which are recorded in a recording device so as to be correlated with each other when the object is generated. The control unit further detects an object which is unnecessary to execute a subsequent program and acquires the time information, and records a difference between the time information at the time of the generation and at the time of the detection in the recording device so as to be correlated with the information of the program.
