Abstract
An image forming apparatus includes first and second image forming portions, a power source portion, and a controller. The power source portion is constituted so that when the power source portion applies a charging voltage to a first charging member of the first image forming portion, the charging voltage is also applied to a second charging member of the second image forming portion. The controller carries out control so that a timing of a start of discharge of a first photosensitive drum in the first image forming portion is made earlier than a timing of a start of image formation by the first image forming portion and so that a timing of a start of discharge of a second photosensitive drum in the second image forming portion is made earlier than a timing of a start of image formation by the second image forming portion.
