    • An information processing apparatus includes a receiving unit, a rasterization processing unit, a saving unit, a detector, a conversion unit, a storage unit, and a removing unit. The receiving unit receives print information described in a page description language. The rasterization processing unit performs a rasterization process of converting the print information into bitmap data. The saving unit saves the bitmap data as cache data for each of objects included in the print information. The detector detects, among the objects included in the print information, an object which is called only once to obtain a detection result. The conversion unit converts, in accordance with the detection result, the object which is called only once for the print information into page data. The storage unit stores the page data. The removing unit removes a command to call, from the saving unit, the object called only once for the print information.
    • 信息处理设备包括接收单元,光栅化处理单元,保存单元,检测器,转换单元,存储单元和去除单元。 接收单元接收以页面描述语言描述的打印信息。 光栅化处理单元执行将打印信息转换为位图数据的光栅化处理。 保存单元将位图数据保存为包括在打印信息中的每个对象的高速缓存数据。 检测器检测包括在打印信息中的对象中的仅被调用一次以获得检测结果的对象。 转换单元根据检测结果将仅打印一次的对象转换为页面数据。 存储单元存储页面数据。 删除单元从保存单元中删除一个命令,用于调用打印信息仅调用一次的对象。

    • A novel electrophotographic photoreceptor and a method of preparation therof are disclosed. The photoreceptor is characterized in that the photosensitive layer contain a specific carbonate resin binder resin having a weight average molecular weight on not less than 200,000. The resin is preferably a polycarbonate resin which contains repeating units represented by the formula ##STR1## wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, R.sup.6, R.sup.7 and R.sup.8 are respectively and independently a hydrogen atom, a lower alkyl group, a halogen atom or an unsubstituted or substituted aromatic group; and R.sup.9 and R.sup.10 are respectively and independently a hydrogen atom, a lower alkyl group, an unsubstituted or substituted aromatic group, or form a ring or a carbonyl group together with the linking carbon atom. The method is characterized in that the photosensitive layer contains a polyocarbonate having a weight average molecular weight of not less than 200,000 as a binder resin and is formed by spray coating or spiral coating.
