    摘要: A high-strength seamless steel pipe for oil wells excellent in sulfide stress cracking resistance which comprises, on the percent by mass basis, C: 0.1 to 0.20%, Si: 0.05 to 1.0%, Mn: 0.05 to 1.0%, Cr: 0.05 to 1.5%, Mo: 0.05 to 1.0%, Al: 0.10% or less, Ti: 0.002 to 0.05% and B: 0.0003 to 0.005%, with a value of equation “C+(Mn/6)+(Cr/5)+(Mo/3)” of 0.43 or more, with the balance being Fe and impurities, and in the impurities P: 0.025% or less, S: 0.010% or less and N: 0.007% or less. The seamless steel pipe may contain a specified amount of one or more element(s) of V and Nb, and/or a specified amount of one or more element(s) of Ca, Mg and REM. The seamless steel pipe can be produced at a low cost by adapting an in-line tube making and heat treatment process having a high production efficiency since a reheating treatment for refinement of grains is not required.

    摘要: A fixing device includes a rotatable fixing member; a heating source configured to heat the fixing member; an opposing member configured to come into contact with an outer circumferential surface of the fixing member to form a nip portion; and a shielding member configured to block heat from the heating source. The shielding member is configured to rotate about a position different from the center of the heating source so as to be movable between a shielding position and a retraction position. The shielding position is a position where the shielding member comes close to the heating source to block heat from the heating source to the fixing member. The retraction position being a position where the shielding member is retracted away from the shielding position.

    摘要: A waste-toner collecting device includes a waste toner collector that collects and stores therein non-transferred toner as waste toner conveyed from a cleaning unit via the conveying path; and a leveling member that levels waste toner accumulated inside the waste toner collector, and drive of which is controlled so that driving conditions thereof are varied based on information of an image formed on the image carrier. The switching of the driving conditions of the leveling member is controlled so as to be performed after a delay time during which the non-transferred toner collected in the cleaning unit reaches the waste-toner collector via the conveying path.
