ABSTRACT:
First and second optical latent image forming devices form an electrostatic latent image directly on a homogeneously charged recording medium surface. Each of the first and second optical latent image forming devices has the capability of discharging almost half the initial charges of the recording medium. The discharging effect of the first and second optical latent image forming devices forms the combined electrostatic latent image.
