Abstract: A band-pass filter separates an audio intermediate frequency signal from an input intermediate frequency signal, and an A/D converter circuit converts the audio intermediate frequency signal into a digital signal. A DSP performs audio detection on the digital signal and forms an AGC signal based on the signal. A variable gain amplifier performs AGC on the audio intermediate frequency signal in response to the AGC signal. A bandpass filter separates and takes out a video intermediate frequency signal from the signal, and an A/D converter circuit converts the video intermediate frequency signal into a digital signal. A DSP performs video detection on the signal. An AGC signal is formed based on the signals and AGC is performed on the video intermediate frequency signals by using the AGC signal.

Abstract: An image forming apparatus has a fixing unit and a control for controlling a peripheral speed of a fixing rotatable member, the following formula being satisfied: Pmin>Lmin 0<X≦&dgr;L/Pmax V0: the peripheral speed; Vf: a feeding speed; Lmin: a minimum path length between a transfer nip and a fixing nip; Lmax: a maximum guide path length between the transfer nip and the fixing nip; &dgr;L=Lmax−Lmin: an amount of loop: Pmax: a maximum length of the transfer material on which toner image may be formed; Pmin: a minimum length of the transfer material on which the toner image may be formed; X: a fluctuation rate of the feeding speed Vf during control of the peripheral speed.

Abstract: An Image forming apparatus includes an image bearing member for carrying a toner image.

Abstract: An image forming apparatus has a transfer unit that transfers a toner image formed and born on an image bearing body onto a transfer material and a fixing unit that fixes the toner image transferred by the transfer unit to the transfer material. A first transfer material supporting unit supports a non-transfer surface of the transfer material separated from the image bearing body at a transfer material outlet of the transfer unit. A second transfer material supporting unit defines an inlet height of the transfer material at the fixing unit and a third transfer material supporting unit is disposed between the first and second transfer material supporting units. The first, second and third transfer material supporting units are located on a substantially straight line.
