ABSTRACT:
An image recording apparatus for recording a latent image of an original color image onto an elongated web photosensitive recording medium by separating the color of the color image into a plurality of colors by creating a plurality of mask members, and exposing the same part of the photosensitive recording medium to each of the plural mask members by appropriately colored light. The tension applied to the photosensitive recording medium is detected by a sensor at a slack buffer location between an exposing unit and a developing unit when development of one latent image and exposure of a following latent image are carried out simultaneously. The driving speed for a motor for driving the buffer is changed by a control unit according to the tension of the photosensitive recording medium as detected by the sensor. Accordingly, when the driving speed of the buffer motor varies relative to speed of the developing unit causing a change in tension applied to the photosensitive recording medium during the simultaneous exposure and development operations, the driving speed of the buffer motor is adjusted by the control unit so that the tension of the photosensitive recording medium is maintained to be constant. Therefore, fluctuation in the tension of the photosensitive recording medium is prevented.
