摘要： 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.

摘要： 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.

摘要： An image forming apparatus includes a transport belt, a first intermediate transfer belt, and a second intermediate transfer belt. The transport belt is disposed along a transport path extending in a vertical direction. The transport belt is configured to transport a recording medium while coming into contact with one surface of the recording medium. The first intermediate transfer belt is configured to sandwich the recording medium together with the transport belt. An image is transferred from the first intermediate transfer belt to the recording medium. The second intermediate transfer belt is disposed above the first intermediate transfer belt. The second intermediate transfer belt is configured to sandwich, together with the transport belt, the recording medium which is in a state where the recording medium is sandwiched between the first intermediate transfer belt and the transport belt. An image being transferred from the second intermediate transfer belt to the recording medium.

摘要： A cleaning device for a rotational body is provided. The cleaning device includes a scraping portion whose edge is pressed against a rotational body to which toner adheres. The scraping portion scrapes the toner off the rotational body. The cleaning device also includes a guide portion that guides a recording medium toward the rotational body, and a guide support portion that supports the guide portion. The guide support portion is disposed at a position separated from the scraping portion in a state in which the guide support portion is pressed by the guide portion that is guiding the recording medium.

摘要： An image forming apparatus includes a fixing unit that transports a sheet of paper carrying an unfixed image through a nip part to fix the unfixed image to the sheet, a first guide unit coming into contact with a side of the sheet that guides transport of the sheet, and a second guide unit coming into contact with an opposite side of the sheet that guides transport of the sheet. The first guide unit has a recess serving as a guide part, the recess being recessed in a direction away from a transport path of the sheet. The second guide unit has a bending part serving as a guide part, the bending part having a shape of a circular arc in cross-section, the bending part being disposed such that at least a portion of the bending part lies inside the recess.

摘要： A sheet transport apparatus includes a first transport device, a second transport device, a first guide member, and a second guide member. The first transport device transports a sheet. The second transport device is disposed downstream of the first transport device in a transport direction and transports the sheet. The first guide member is disposed between the first and second transport device such that the second transport device is closer to the first guide member than the first transport device and guides the sheet to the second transport device. The second guide member is disposed between the first and second transport device such that the first transport device is closer to the second guide member than the second transport device and guides the sheet to the first guide member while curving the sheet.
