Abstract: The present invention provides a sheet supplying apparatus comprising a sheet supporting means for supporting a sheet, a sheet supply means supported to contact with and separate from the sheet supported by the sheet supporting means and adapted to feed out the sheet by contacting with the sheet, a first biasing means for biasing the sheet supporting means toward the sheet supply means, and a second biasing means for biasing the sheet supply means toward the sheet supported by the sheet supporting means.

Abstract: In a fixing device, a core material of a fixing rotating member has two largest-diameter portions respectively located between a central portion and each end portion of the fixing rotating member, within a region where a recording material of a largest size passes, and the diameter of each core material is gradually reduced from the largest-diameter portion toward the central portion and toward the nearest end portion. The outer shape of the fixing rotating member conforms to the shape of the core material. According to this configuration, it is possible to prevent corrugation and curl of the recording material, and to provide excellent mountability of the recording material.
