Abstract
An image forming apparatus includes a reading unit for reading an original image, and a recording unit for recording an image. A control unit is also provided which controls the relative timing between the operations of the reading unit and the recording unit. The operation of the control unit enables the apparatus to perform a reading operation in a first mode, in which the reading unit reads an original image without the recording unit performing a recording operation, in parallel with a recording operation in a second mode, in which a different original image, read by the reading unit, is recorded by the recording unit, such that vibrations caused by either the reading operation in the first mode or the recording operation in the second mode do not affect the other operation. As a result of the structure of the apparatus, an advantageous feature can be attained in which the timing of a writing operation is controlled in accordance with the movement of the reading scanner.
