The present invention provides a drive device having slip stoppers that can reliably prevent skewed movement of or damage to a belt.The drive device pertaining to the present invention has a roller, a drive roller, a belt that is suspended and moves over these rollers, and slip stoppers that are mounted to the roller and prevent the belt from moving in a skewed fashion. The slip stopper comprises a base into which the roller is inserted, a first wall that is located on the edge of the base that faces the belt and that is essentially perpendicular to the inner surface of the base and a second wall that extends outward continuously from the first wall and is tilted toward the other edge of the base.

In a belt type fixing apparatus having a heat roller temperature sensor that detects the temperature of a heat roller that contains a heater for heating a fixing belt, and a fixing belt temperature sensor that is set to contact a pressure roller and indirectly detects the temperature of the fixing belt, the heater that heats the fixing belt is controlled in such a way that the temperature detected by the heat roller temperature sensor matches the target temperature of the heat roller that is set based on the temperature detected by the fixing belt temperature sensor.

A fixing apparatus includes a fixing belt that pressure-thermally fixes unfixed toner images on sheets, and an oil coating roller that holds silicone oil for preventing the offset phenomenon to be coated on the fixing belt. The oil coating roller consists of an inner oil holding layer formed of paper and a surface oil holding layer formed of aramid fibers. The oil diffusing capacity and the oil holding capacity are reduced from the inner oil holding layer toward the surface oil holding layer. Thus, it is possible to suppress the oil coating amount in the initial period of the roller life to a level that does not cause problems such as oil stains, increase the oil coating amount in the final period of the roller life to a level that does not cause problems such as offsets, and prevent image noises.

A fusing belt type heat fusing device has a rotating fusing roller, a driven heating roller, an endless fusing belt wrapped and stretched around the two rollers, a pressure roller that applies pressure to the fusing roller through the fusing belt, and a separation agent application and tension transmission element that applies an offset suppression separation agent to the fusing belt in addition to transmitting tension to the fusing belt. The separation agent application and tension transmission element is installed so as to make contact with the fusing belt at an upstream side of the heating roller in the rotation direction of the fusing belt between the fusing roller and the heating roller and at a position closer to the heating roller than a center position between the fusing roller and the heating roller.

A fusing device has a pair of fusing rollers of which at least one is covered by an elastically deformable layer of heat resistant material with the fusing rollers being brought into contact with each other; a recording material guide member and a pre-heating member having a plane-shaped heating surface opposite to the recording material guide member on an upstream side recording material which maintains a toner image away of a nip portion where the fusing roller make contact. While the recording material which maintains the toner image is guided on said recording material guide member, the toner image is heated by means of the pre-heating member and passed through the nip portion. The fusing device is set to satisfy the relationship of 0

In a nest MZI modulator in which each arm includes a child MZI, the power consumption is reduced. The hybrid integrated-type nest MZI modulator of the embodiment 1a is configured so that, instead of placing a relative phase adjusting section in a parent MZI, a bias electrode Bias 90° in which an electric field is applied in the same direction to the polarization direction in both of the upper and lower arms is placed in each child MZI (see FIG. 4B). The bias electrode Bias 90° provided in each child MZI constitute the entirety of a relative phase adjusting section. The optical signals are subjected to a phase change after the output from the child MZI (see FIG. 1A), because such relative phase adjusting section can subject the optical signals of the upper and lower arms of the child MZI to a shift change in the same direction, respectively.

A vehicle power-supply control device has a battery charger that converts an externally-supplied AC voltage into a DC voltage used to charge a vehicle high-voltage battery, a low-voltage power generator that converts the DC voltage output from the battery charger into a DC voltage used to drive a vehicle auxiliary machine, and a controller that controls the battery charger and the low-voltage power generator. The battery charger includes a power factor correction circuit that corrects a power factor of the AC voltage and a first DC/DC converter that generates a predetermined DC voltage based on an output of the power factor correction circuit. The low-voltage power generator includes a second DC/DC converter that steps down the DC voltage output from the battery charger and a synchronous rectifier that rectifies an output of the second DC/DC converter in synchronization with a switching operation of the second DC/DC converter.
