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: The purpose of the present invention is to provide a cellulose acetate excellent in transparency, and a molded article of the cellulose acetate. In the cellulose acetate, an acetylation degree is 52% or more and 59% or less, and a content of low-molecular-weight components having a molecular weight of not more than ¼ of a peak top molecular weight in a molecular weight distribution measured by gel permeation chromatography of cellulose acetate is 12% or less.

Abstract: A method for producing ammonia involves producing ammonia from molecular nitrogen in a production apparatus for performing electrolysis by supplying electrons from a power source, protons from a proton source and molecular nitrogen from a device for supplying a nitrogen gas while in the presence of a solid catalyst and a complex in a cathode. For example, a molybdenum complex represented by formula (A1) or formula (B2) as the complex, and a platinum catalyst or a platinum catalyst/gold catalyst combination as the solid catalyst are used.

Abstract: An ammonia production method is a method of producing ammonia from nitrogen molecule using electron supplied from a power supply in the presence of a complex and a proton source. The complex used is, for example, a molybdenum complex (1) that is carried on Merrifield resin.

Abstract: The purpose of the present invention is to provide cellulose acetate with which it is possible to obtain a molded article containing cellulose acetate having a small amount of lumps. The cellulose acetate has an acetylation degree of 52% or more and 59% or less, and an acetone-insoluble substance content of 0.04 wt % or less.

Abstract: The purpose of the present invention is to provide cellulose acetate excellent in transparency. The method for producing cellulose acetate flakes includes the steps of (a) generating a cellulose acetate dope by reacting cellulose with acetic anhydride in a presence of an acid catalyst and an acetic acid solvent; (b) hydrolyzing the generated cellulose acetate to adjust an acetylation degree to 52% or more and 59% or less; (c) precipitating the adjusted cellulose acetate in a presence of water; (d) forming the cellulose acetate obtained by precipitation into a slurry by dispersing the cellulose acetate in a mixed solvent including a solvent having a solubility parameter ? of 8 to 13 and a solvent having a solubility parameter ? of 14 or more; and (e) separating the cellulose acetate from the slurry to form the cellulose acetate into flakes, the mixed solvent containing 30% by weight or more and 70% by weight or less of the solvent having a solubility parameter ? of 8 to 13.
