An image forming apparatus includes an image bearing member; an endless belt; a first driver for driving the belt in contact to an inner surface of the belt; a second driver for driving the belt in contact to an outer surface of the belt; and a tension detector for detecting a state of tension of the belt. The tension detector includes: a movable device, contacted to the belt in a region downstream of the second driver and upstream of the first driver and in a region upstream of the second driver and downstream of the first driver with respect to a rotational direction of the belt, capable of moving its position depending on the tension of the belt in the two regions; a member-to-be-detected capable of changing its position in interrelation with the movement of the movable device; and a detecting device for detecting the member-to-be-detected.

A circuit for discriminating a ‘Noisy’ state of an output of a squelch circuit is disclosed. A circuit for resolve the ‘Noisy’ state of the output of the squelch circuit is also disclosed which uses the output identification circuit. The output of the squelch circuit and a clear signal are input into a first AND gate. The output of the first AND gate is input into a first flip-flop. An inversed signal of the output of the first AND gate is input into a second flip-flop. The outputs of the first and second flip-flops are input into a discriminating unit including a second AND gate. The ‘Noisy’ state is identified by the output of the second AND gate. Based on the identification result, sensitivity of the squelch circuit is regulated.

The image forming apparatus includes an image bearing member, a first motor for driving said image bearing member, a fixing unit which fixes an image transferred from said image bearing member to a recording material onto the recording material and a second motor for driving said fixing unit, wherein said fixing unit is started up by said first motor and then driven by said second motor. Thereby, costs on the second motor for driving the fixing apparatus, which is disposed separately from the first motor for driving the image forming apparatus, can be restrained.

A swash plate of a swash-plate compressor is subjected to sliding on shoes and is required to have excellent seizure resistance and wear resistance under the dry lubricating condition. The swash plate according to the present invention is provided with the surface-treated layer, i,e., the intermediate layer consisting of Cu, Sn or metal phosphate, and a sliding contact layer consisting of MoS.sub.2 and/or graphite and thermosetting resin.

An image forming apparatus includes an image bearing member for bearing a toner image, a rotatable endless belt, a first driving member for rotationally driving the endless belt and in contact with an inner peripheral surface of the endless belt, and a second driving member for rotationally driving the endless belt and in contact with an outer peripheral surface of the endless belt. In addition, a tension detecting unit detects a state of tension of the endless belt and a controller controls a rotational speed of the second driving member. A driving force applied from the second driving member to the endless belt is smaller than a driving force applied from the first driving member to the endless belt, and the tension detecting unit includes a metal roller contacting the inner peripheral surface of the endless belt and detects the tension by movement of the metal roller which follows the endless belt. The controller controls, on the basis of a detection result of the tension detecting unit, the rotational speed of the second driving member so that the state of tension of the endless belt is a predetermined state.
