An image forming apparatus is provided that can prevent a winding jam of a sheet, which can be caused owing to curling of the sheet at the front end in the sheet conveying direction.

Image forming apparatus including a temperature difference providing unit providing a relative temperature difference for a conveyed sheet

A toner collecting apparatus which transports collected toner through a discharge pipe to discharge the collected toner from a discharge port of the discharge pipe, the toner collecting apparatus including: a cover pipe having an open window and being rotatable around the discharge pipe in a substantially concentric fashion; a protective wall covering at least apart of the cover pipe; and a rotation member which rotates the cover pipe, wherein the cover pipe is rotated by the rotation member between an open position in which the open window is aligned with the discharge port and a closed position in which the open window is shifted from the discharge port so that at least the open window is covered with the protective wall.

Toner collecting apparatus, cartridge, and image forming apparatus

A coil springis provided in an empty room (inside of a fixing roller) of a main bodyof a roller. The coil springis in contact with an inside wallsurrounding the empty room of the roller main bodyand pushes the inside walloutward. The coil springand the inside wall faceare coated with a black filmexcept the contact portionof the coil springand the inside wall

Fixing roller, and method of producing the same, fixing device and image forming device

A developing apparatus prevents magnetic toner rise on the peripheral face of the developing sleeve to avoid scatter of magnetic toner even when a gap is caused between the developing blade and the magnetic sealing member. A magnetic plate of a base part and a protruding part, where the base has a rectangular cross-section and is in the shape of an arc extends along the peripheral face of a developing sleeve. The protruding part is on the upstream side of a doctor blade in the rotation direction in the middle of the base part in the arc length direction. The protruding part protrudes nearly perpendicularly from the side face which is perpendicular to the peripheral face of the developing sleeve, so as to cover the regions of the peripheral face of the developing sleeve from the base part to the portion facing the doctor blade.
