Abstract: A fixing device includes a fixing part in which an image on a recording material is fixed, and a guiding member provided on an upstream side with respect to the fixing part in a direction of transport of the recording material. The guiding member guides the recording material toward the fixing part while, if the recording material that is being transported is skewed, reducing a speed of movement of a preceding part of a leading end of the recording material. The preceding part is ahead of any other part of the leading end of the recording material.

Abstract: A paper transporting device includes a driving roller member, a driven roller member, a first guiding member and a second guiding member. The driving roller member is rotated. The driven roller member is rotated in contact with the driving roller member. The first guiding member is disposed on a driving roller member side, and guides a paper to a contact portion in which the driving roller member and the driven roller member are in contact with each other. The second guiding member is disposed on a driven roller member side, and guides the paper to the contact portion. The second guiding member partially protrudes inward in a radial direction of the driving roller member from an outer peripheral surface of the driving roller member at a downstream side in a paper transporting direction of the contact portion.

Abstract: A fixing device includes a rotatable body; a rotatable endless belt having inner and outer peripheral surfaces; a first presser portion within the inner peripheral surface and pressing the outer peripheral surface onto the rotatable body to form a first nip, through which a recording medium passes, between the endless belt and the rotatable body; and a second presser portion within the inner peripheral surface and pressing the outer peripheral surface onto the rotatable body to form a second nip through which the recording medium passes. The first nip decreases in length in a recording-medium transport direction from a central area toward opposite ends in an axial direction. The second nip increases in length in the transport direction from a central area toward opposite ends in the axial direction, and has an upstream edge, in the transport direction, whose central area protrudes upstream relative to the opposite ends.
