摘要： In a fixing unit in which a recording material carrying a toner image is heated while conveying in a nip portion to fix the toner image onto the recording material, a measure is required, which can to prevent both of temperature rise at non-sheet-passing area and condensation slippage using at least one air supplying unit. Separately providing air supplying units for these two issues results in the need of a plurality of fans only for the fixing unit, increasing the size and cost of the apparatus. Thus, decreases in size and cost of a fixing unit and an image forming apparatus including the fixing unit can be achieved by using a common air supplying member to prevent both of temperature rise at non-sheet-passing area and condensation slippage.

摘要： An image forming apparatus includes a main assembly; a cartridge for forming a toner image on a sheet material; a fixing unit for fixing the toner image on the sheet material; and an opening for exposing an inside of the main assembly. The fixing unit and the cartridge are mountable into the main assembly and are disposed side by side. When the fixing unit and the cartridge are mounted or demounted, the fixing unit passes through the opening, and the cartridge passes through a space in which the fixing unit is to be mounted and passes through the opening. When the fixing unit and the cartridge at the time of passing through the opening are projected onto a surface perpendicular to a mounting and demounting direction, a contour of a projected area of the cartridge is at least partly inside a contour of a projected area of the fixing device, and the cartridge passes through the inside of the contour of the projected area of the fixing device when passing through the opening.

摘要： A sheet supply portion is disposed in the lowermost portion of a printer so as to be substantially horizontal. A main conveying path for guiding a sheet from a transferring roller to a fixing device is disposed in a substantially vertical direction so as to be along the back of the printer. The guide surface of a sheet delivery guide constituting a conveying path leading from the fixing device to a pair of sheet delivery rollers is a flat surface.

摘要： An image forming apparatus includes a main assembly; a cartridge, detachably mountable to the main assembly, for being operated so as to form a toner image on a sheet material in a state in which the cartridge is mounted in the main assembly; a fixing unit, detachably mountable to the main assembly, for fixing the toner image on the sheet material; and an opening for exposing an inside of the main assembly. The fixing unit and the cartridge are mountable into and demountable from the main assembly in a mounting and demounting direction in which the fixing unit and the cartridge are disposed side by side. When the fixing unit and the cartridge are mounted into and demounted from the main assembly, the fixing unit passes through the opening, and the cartridge passes through a space in which the fixing unit is to be mounted and passes through the opening. When the fixing unit and the cartridge at the time of passing through the opening are projected onto a surface perpendicular to the mounting and demounting direction, a contour of a projected area of the cartridge is at least partly inside a contour of a projected area of the fixing device, and the cartridge passes through the inside of the contour of the projected area of the fixing device when passes through the opening.
