A drum idle rotation is executed by the timing before printing on the basis of the number of drum idle rotating times selected by the operator, or the number of drum idle rotating times is set in accordance with a print image kind or a drum count value and the drum idle rotation is performed by the timing before printing on the basis of the set value. The number of drum idle rotating times by the timing before printing is corrected by a print density or an apparatus environment. Defective exposure or generation of a lateral stripe due to oligomer which is generated in the portion where a developing roller or a photosensitive drum is come into contact is prevented.
