    摘要: An image forming apparatus such as a laser beam printer has a plurality of movable image carrying members such as photosensitive drums, an image forming member such as a laser beam scanner capable of forming on the image carrying members images of different colors correspoding to image information, and transfer devices for sequentially transferring the image carried by the image carrying members to an image receiving member such that the image of different colors are superposed. The image receiving member may be copy paper or an overhead projector sheet, and is fed by a feeding device in the form of an endless belt. A lifting device is provided to move the feeding device from an operative position to at least one retracted position in response to detection of jamming or when an image receiving member having a large heat capacity is used.

    摘要: An image forming apparatus in which a recording material having an unfixed image formed thereon by an image forming device is conveyed to a fixing device having a pair of rotatable members by a conveyor and the recording material is nipped and conveyed by the pair of rotatable members so that the unfixed image is fixed on the recording material. The pair of rotatable members is selectively rotatable at a first peripheral speed lower than the speed at which the conveyor conveys the recording material and a second peripheral speed higher than the first peripheral speed. The pair of rotatable members are rotated at the first peripheral speed to convey the recording material and form a loop of recording material rearwardly of the pair of rotatable members with respect to the direction of conveyance of the recording material, whereafter the peripheral speed of the pair of rotatable members is changed over from the first peripheral speed to the second peripheral speed to suppress the growth of the loop of the recording material.
