Abstract
An image forming apparatus includes an image carrier, and a rotation device having image-forming devices each containing a toner and forming a toner image on the image carrier with the toner. The apparatus further includes: a detector attached to at least one of the image-forming devices to detect a quantity of the toner, thereby outputting an analog signal representing the quantity; and a transmission path transmitting the analog signal to the outside of the rotation device. The transmission path includes: a rotation terminal mounted on and rotating with the rotation device; and a contact terminal provided outside the rotation device, and maintaining continuity with the rotation terminal by contacting a surface of the rotation terminal even when the rotation terminal rotates. The apparatus further includes a correction section correcting the analog signal transmitted by the transmission path, according to a contact resistance between the rotation terminal and the contact terminal.
