An image data storing device for an image forming apparatus having a plurality of line buffers to which image data are written from external equipment and from which the written image data are read to form an image. Selectors selectively cause the individual buffers into a read state, write state, and inoperative state. An image forming signal generator generates an image forming signal during one frame of image forming period. During an image forming period, the selectors condition each of the line buffers for any one of the above-mentioned three different states while, during a non-image forming period, they hold the line buffers in the individual states. This allows the line buffers to start operating under the same conditions whenever an image forming period is reached.
