摘要： A process for manufacturing a rare earth-iron-boron alloy permanent magnet by, after sintering, keeping the sintered alloy at temperatures of 750.degree.-1000.degree. C. for 0.2-5 hours, slowly cooling it at a cooling rate of 0.3.degree.-5.degree. C./min. to temperatures between room temperature and 600.degree. C.; annealing it at temperatures of 550.degree.-700.degree. C. for 0.2-3 hours, and rapidly cooling it at a cooling rate of 20.degree.-400.degree. C./min. The permanent magnet contains a matrix, a B-rich phase and a Nd-rich phase. In grain boundaries of the matrix phases covered by bcc phases, thin, fine plates of the bcc phases projecting into the matrix phases are once increased by the first heat treatment and slow cooling and then eliminated by the annealing.

摘要： An image forming apparatus includes a body frame, a transport unit, an image carrier, a transfer device, a fixing device, a guide member assembly, a door, and a positioning member. The guide member assembly includes a guide member, a positioned portion, and a support member. The support member supports the guide member and has a side wall that extends in such a direction as to intersect a line drawn in the width direction and that has a hole through which a support shaft is inserted with some play being present. The guide member assembly is supported by the door with some play being present between the guide member assembly and a base plate and is urged by an urging member. The hole is a long hole having a major axis extending in an opening direction of the door away from a center line of rotation of the door.
