    摘要: A magnetic powder for magnetic recording medium comprises acicular particles constituted primarily of Fe, wherein the powder contains Co in an amount such that the Co/Fe ratio is 50 at. % or less and the Co is contained in a manner such that the surface portion has a higher concentration than the core portion of the particles, and upon subjecting the magnetic powder for magnetic recording medium to TG measurement, the powder exhibits at least two oxidation starting points: a low-temperature side oxidation starting point and a high-temperature side oxidation starting point. The magnetic powder achieves improved resistance to oxidation without sacrificing magnetic characteristics.

    摘要: An image forming apparatus according to the invention includes a first sheet-transfer unit for transferring a sheet, a second sheet-transfer unit for transferring downstream the sheet transferred from the first sheet-transfer unit, and a pivotable member for supporting either the first sheet-transfer unit or the second sheet-transfer unit. When an abnormal transfer state of a sheet is detected in the image forming apparatus, a controller controls driving at least one of the first sheet-transfer unit and the second sheet-transfer unit so as to move the sheet which stops spanning the first and second sheet-transfer units by a predetermined amount of movement, thereby forming a loop in the sheet.
