    • A color image forming apparatus including an image bearing member movable along an endless path, on which color toner images are formed, a transfer material supporting member movable along an endless path for supporting a transfer material and conveying it to an image transfer position where the color toner images are superimposed and transferred sequentially to the transfer material. Also provided are a first driving motor for driving the image bearing member, and a second driving motor, separately provided from the first motor, for driving the transfer material supporting member. In addition, the apparatus includes a detector for detecting the speed of the surface of the transfer material, a discriminator for determining whether the speed variations detected by the detector are within a tolerable range, and a control, responsive to the discriminator, for stopping the operation of a subsequent image transfer step when the detected speed variation is beyond the tolerable range, and for repeating latent image forming, developing, and transfer steps.

    • The present invention provides an apparatus wherein image fixing means is controlled for different fixing conditions under which a toner image is fixed on a recording material to adapt it to a synthetic resin sheet as the recording material or to a color image to be fixed, including at least one of fixing temperature, fixing speed and actuation of cleaning means. The present invention is particularly effective in use for a recording system in which the fixing temperature and speed are decreased and the cleaning means is actuated when a color image is to be formed on a transparent or resin sheet. The present invention is most useful for a color image recording system.
    • 本发明提供了一种装置,其中控制图像定影装置用于不同的定影条件,在该条件下,将调色剂图像固定在记录材料上以适应于作为记录材料的合成树脂片或要固定的彩色图像,包括在 定影温度,定影速度和清洁装置的致动中的至少一个。 本发明特别有效地用于其中定影温度和速度降低并且当在透明或树脂片上形成彩色图像时清洁装置被致动的记录系统。 本发明对于彩色图像记录系统是最有用的。
