A clock control apparatus which generates a clock for laser drive in latent image formation in an image forming apparatus. A main-scanning synchronizing clock generation unit 603 generates a synchronizing clock synchronized with a main-scanning synchronizing signal based on the main-scanning synchronizing signal and an original clock. A delay unit 604 delays the synchronizing clock so as to correct a mechanical shift upon latent image drawing by laser drive. A pseudo main-scanning synchronizing signal generation unit 103 generates a pseudo main-scanning synchronizing signal based on the synchronizing clock delayed by the delay unit 604, and supplies the pseudo main-scanning synchronizing signal to the main-scanning synchronizing clock generation unit 603. The main-scanning synchronizing clock generation unit 603 generates a clock synchronized with the pseudo main-scanning synchronizing signal. The clock is supplied via a clock selection unit 102 to a PWM generation unit 605, and is used for the laser drive.
