Abstract
A latent electrostatic image is formed on a rotatable latent image carrying body in a matrix form by an electrostatic recording head. An encoder outputs a pulse signal having a period which reflects a rotational speed of the latent image carrying body. A timing signal to be used for driving the recording head is generated based on the pulse signal and control information which has been produced based on the pulse signal and indicates a proper drive period of the timing signal. In another method, the period of the pulse signal is corrected so as to become consistent with a pitch, in the rotational direction of the latent image carrying body, of matrix elements of the recording head. The timing signal is generated based on the corrected pulse signal.
