ABSTRACT:
An image forming apparatus forms a latent image on a photoconductive member by scanning a light beam with a rotational deflector, and forms a visual image on a sheet without temporarily stopping the sheet on a sheet conveyance path. The image forming apparatus includes a motor that drives the rotation deflector when an image formation instruction is given, a rotation status-determining device that determines if the motor driven the rotation deflector reaches steady state, and a sheet feed control device that starts conveying the sheet (from a starting position of the sheet conveyance path) when the rotation status-determining device determines that the motor reaches the steady state. A detection device detects a passage time when the sheet passes a prescribed position on the sheet conveyance path. A latent image formation control device starts forming a latent image on the photoconductive member based on the passage time.
