摘要： An image forming apparatus includes an endless belt, a pair of belt winding rollers that wind and rotate the endless belt, and a belt shift detecting device that detects a belt shift. The image forming apparatus further includes a roller end moving device that moves one end of one of the belt winding rollers around its other end in response to the detection of a belt shift to suppress the belt shift to a predetermined range, and a belt surface contacting device that pressure contacts the surface of the endless belt. The belt surface contacting device is mounted on a frame that supports a shaft of the belt winding roller to be moved so that its contacting condition does not change during the movement of the belt winding roller moved by the roller end moving device.

摘要： Disclosed is a light source device including a light source that includes a light emitting tube; and a cooler configured to cool the light emitting tube. The cooler includes an inlet port for drawing cooling air for cooling the light emitting tube; a flow channel that extends from the inlet port to the light emitting tube in a horizontal direction and that is for flowing the cooling air toward the light emitting tube; and a baffle plate that is disposed in the flow channel and that can slide in a gravity direction. The baffle plate has a shape and openings such that, in an installation state, an upper portion of the flow channel is opened and a lower portion of the flow channel is closed by the shape and positions of the openings of the baffle plate.
