Abstract: An image forming apparatus includes a sheet feeding cassette, transport rollers, a pick-up roller, a sheet detector, and a control section. The sheet feeding cassette stores sheets for developer images to be transferred thereonto at a secondary transfer position. The transport rollers transport a sheet at variable speeds along a sheet transport path which extends from the cassette to the secondary transfer position. The pick-up roller feeds a sheet into the sheet transport path. The sheet detector detects whether a sheet is fed from the cassette. When the detector detects that a sheet is not fed, the control section controls the pick-up roller to feed the sheet again. The control section varies respective transport speeds of the pick-up roller, a sheet feed roller, and the transport rollers, according to number of attempts to feed the sheet.

Abstract: Claw-shaped magnetic poles are alternately disposed along the rotation plane of a rotor of an electric rotating machine, and a permanent magnet is disposed between the claw-shaped magnetic poles. Surface of the permanent magnet is coated with a coating layer. The coating layer is composed of a anticorrosive material performing sacrificial anticorrosion (metal flake in a coating film rusts prior to a matrix resulting in protection of the matrix) such as inorganic material containing zinc and a film of the anticorrosive material is formed by spraying. Ionization tendency of zinc is larger than that of iron composing the permanent magnet, and the permanent magnet is difficult to be rusted owing to the sacrificial anticorrosion. Consequently, anticorrosion of the permanent magnet disposed between the claw-shaped magnetic poles is improved.
