Abstract
An image forming apparatus includes: an image forming section; and one or more controllers that control the image forming section. At the time of start-up of the image forming section, the one or more controllers perform predetermined determination processing by which both a contact state between a photoreceptor and a transfer section and a contact state between the photoreceptor and a charging section are determined, when determining that the photoreceptor is in the contact state with the transfer section and the photoreceptor is in the contact state with the charging section, the one or more controllers determine normality, and when determining that the photoreceptor is not in the contact state with the transfer section or the photoreceptor is not in the contact state with the charging section, the one or more controllers determine that abnormality has occurred and limit operation of the image forming section to a predetermined operation.
