Abstract
In an electrophotographic printing apparatus, when the conveying speed of the timing roller (,) is Vt, the conveying speed of the register roller (,) is Vr, the peripheral speed of the photoreceptor drum (,) is V0, and the conveying speed of the conveying apparatus (,) is Vf, each speed is set to satisfy the relationship of Vf>V0≧Vr>Vt, and when a sheet deflection amount formed when the sheet comes into contact with the register roller, is &dgr;r, the sheet deflection amount at the photoreceptor drum entry section is &dgr;0, and the sheet length is Lp, each value is regulated so that the relationships of &dgr;r≧Lp ((Vr−Vt)/Vt) and &dgr;0≧Lp ((Vf−V0)/V0) are satisfied.
