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 image forming apparatus includes a first rotatable member, a second rotatable member, an air nozzle, and a pipe. The pipe includes a portion extending along a widthwise direction of the first rotatable member perpendicular to a recording material feeding direction.

Abstract: An image forming apparatus includes a reception unit to receive a job, heating and pressing rotary members to form a nip portion, and a spraying member having a nozzle and a cylinder. The nozzle discharges air to the heating rotary member and a recording material. During a period after the reception unit receives the job and before a leading edge of a first sheet of the recording material reaches the nip portion, the spraying member performs a spraying operation of spraying air in an amount greater than or equal to a predetermined amount. The air that the spraying member sprays on the first sheet of the recording material during the job is higher in temperature than the air that the spraying member sprays during the period after the reception unit receives the job and before the leading edge of the first sheet of the recording material reaches the nip portion.

Abstract: An object of the present invention is to provide a resin composition for reducing an acetic acid odor that is generated during melt molding of a polyvinyl alcohol (PVA)-based resin and may remain in a molded product. The resin composition of the present invention contains: a PVA-based resin (A); and a multimeric aldehyde compound (B), wherein a content of the multimeric aldehyde compound (B) is 0.5×10?4 to 100×10?4 parts by weight with respect to 100 parts by weight of the PVA-based resin (A).

Abstract: An object of the present invention is to provide polyvinyl alcohol resin composition pellets in which coloring is small and hardness characteristics are improved. The present invention relates to polyvinyl alcohol resin composition pellets, which comprise a polyvinyl alcohol resin, and have hardness of 100 N or more at 23° C. and 50% RH, and a yellow index value of 50 or less after being heated at 210° C. and pressed at 5 kgf/cm2 for two minutes.

Abstract: A resin composition contains: (A) a polyvinyl alcohol resin; and (B) a block copolymer having a polymer block (b1) of an aromatic vinyl compound, and at least one of a polymer block (b2) of a conjugated diene compound or isobutylene and a hydrogenation block (b3) resulting from hydrogenation of the conjugated diene compound or isobutylene; wherein the polymer block (b1) of the aromatic vinyl compound is present in a proportion of not less than 10 wt. % based on the total amount of the polyvinyl alcohol resin (A) and the block copolymer (B).
