Abstract: An image forming apparatus includes a first rotatable member, a second rotatable member, an air nozzle, and a pipe. The pipe includes a portion provided in a range overlapping with the first rotatable member and making one reciprocation or more in a case that when a direction crossing a feeding direction of a recording material fed in a nip is a widthwise direction of the first rotatable member, the pipe is viewed in a direction perpendicular to the widthwise direction.

Abstract: An ink tank includes an ink storage portion configured to store ink, and a flexible damper portion configured to communicate with an inside of the ink storage portion through a communication hole. A protruding portion protruding from an ink storage portion side toward an inside of the damper portion is formed in the inside of the damper portion. When viewed from a direction in which the protruding portion protrudes, the damper portion surrounds an entire circumference of the communication hole, and an opening portion is formed in the protruding portion.

Abstract: A fixing apparatus includes a belt, a steering roller, a slide member, and a pressing rotation member that forms a nip portion by pressing the belt and is disposed to face the slide member. The belt applies heat to a recording material and has an inner circumferential surface that receives a lubricant applied onto the inner circumferential surface. The pressing rotation member fixes a toner image onto the recording material by applying heat and pressure to an unfixed toner image in the nip portion, in cooperation with the belt. An end portion of the belt on one end side in a belt width direction takes a position outside an end portion of the slide member on the one end side and a position inside the end portion of the slide member on the one end side while the steering roller is in operation.

Abstract: A fixing apparatus includes a belt, a rotary member, a pad member, and a slide member. A distance in the conveyance direction between a first position and a second position is 3.0 mm or less. The first position is a downstream edge of a tip of a projection positioned most downstream in a direction of rotation of the belt. The second position is an upstream edge, in the direction of rotation of the belt, of the guide portion that contacts with the inner circumference surface of the belt. A distance in the pressing direction between a third position and a fourth position is 0.4 mm or more and 2.0 mm or less. The third position is the tip of the projection positioned most downstream in the direction of rotation of the belt. The fourth position is the same position as the second position.
