    • The present invention provides an image forming apparatus comprising an image bearing member, and a recording material bearing member for bearing a recording material to convey the recording material to a transfer station where an image is transferred from the image bearing member onto the recording material borne on the recording material bearing member. The recording material bearing member is capable of bearing a plurality of recording materials simultaneously at different positions thereon. The images can be successively transferred onto first and second surfaces of each recording material, and, when images are formed on the second surfaces of the plurality of recording materials, during a time period in which an area of the recording material bearing member with which the first surface of the recording material was previously contacted is passing through at least the transfer position without bearing the recording material, a spacer particle layer is formed between the image bearing member and the area.
    • 本发明提供了一种图像形成装置,包括图像承载部件和用于承载记录材料的记录材料承载部件,以将记录材料传送到转印站,转印站将图像从图像承载部件转印到承载部件上的记录材料上 记录材料承载部件。 记录材料承载构件能够在其上的不同位置同时承载多个记录材料。 可以将图像依次转印到每个记录材料的第一表面和第二表面上,并且当在多个记录材料的第二表面上形成图像时,在记录材料承载部件的区域 预先接触的记录材料的第一表面至少通过转印位置而不承载记录材料,在图​​像承载部件和区域之间形成间隔颗粒层。

    • An image forming apparatus includes an image carrier for carrying an image, and a transfer medium bearing member for bearing and conveying a transfer medium to a transfer unit of said image carrier. The transfer medium bearing member is able to bear multiple transfer media concurrently. The apparatus includes transfer device for transferring the image of the image carrier onto the transfer medium borne on the transfer medium bearing member in the transfer unit, and a plurality of transfer media capable of being borne on the transfer medium bearing member concurrently, wherein in consecutively transferring the image onto the transfer media of the number not divisible by the maximum sheet bearing number by which said transfer medium bearing member is capable of bearing the transfer media concurrently. The number of transfer media that the transfer medium bearing member concurrently bears at the n-th time where n is a natural number equal to or greater than two, is not less than the number of transfer media that it bears concurrently at the n-1-th time. In transferring the image consecutively as above, the number of sheets that the transfer medium bearing member concurrently bears at the final time is greater than the number of transfer media that the transfer medium bearing member concurrently bears at the first time.
    • 图像形成装置包括用于承载图像的图像载体和用于将转印介质传送到所述图像载体的转印单元的转印介质承载部件。 转印介质承载构件能够同时承载多个转印介质。 该装置包括用于将图像载体的图像转印到承载在转印单元中的转印介质承载构件上的转印介质上的转印装置,以及能够同时承载在转印介质承载构件上的多个转印介质,其中连续地 将图像转印到不能被所述转印介质承载构件同时承载转印介质的最大纸张轴承数量的数量的转印介质上。 转印介质轴承部件在n为自然数以上的第n时间同时承载的转印介质的数量不小于其在n-1处同时存在的转印介质的数量 第一次。 在如上所述连续传送图像时,转印介质承载部件最后同时承载的纸张数量大于转印介质承载部件在第一次同时承载的转印介质的数量。
