    摘要： An image forming apparatus, which is configured to form an image on a sheet, includes an image forming unit configured to form an unfixed toner image on the sheet, and a fixing unit configured to fix the unfixed toner image to the sheet by heating the sheet bearing the unfixed toner image while conveying the sheet by a fixing nip portion. The image forming apparatus can perform a cleaning mode for cleaning the fixing unit by conveying a sheet with an unfixed toner image for cleaning formed thereon by the fixing nip portion. At a time of the cleaning mode, the image forming unit forms the unfixed toner image for cleaning on a sheet surface opposite from a sheet surface where the unfixed toner image is formed at a time of image formation.

    摘要： Provided is an oriented laminated film, characterized in that the film is obtained by alternately laminating Layer A and Layer B such that reflection is generated by optical interference due to a difference in refractive indices of Layer A and Layer B, wherein Layer A includes an aromatic polyester containing trimethylene-2,6-naphthalenedicarboxylate as a main repeating unit and has a layer thickness in a range of 0.05 to 0.5 μm and Layer B includes a polylactic acid composition and has a layer thickness in a range of 0.05 to 0.5 μm, and a reflectivity curve thereof for light in a wavelength range of 400 to 1,600 nm has a reflection peak having a maximum reflectivity which is at least 20% higher than the reflectivity baseline. The present invention can provide a laminated film having high reflectivity with improved thickness variation associated with stretching treatment and improved hue irregularity attributable to a state of lamination.

    摘要： In an image forming apparatus, a first sequence group operates after input of a print signal and a second sequence group is started up at timing when a temperature T of a fixing device has reached a certain temperature T1 after the input of the print signal or timing for which a temperature rising curve is calculated from a time for the temperature T to reach a certain temperature T2 from the temperature T1 during temperature rising of the fixing device. With this image forming apparatus, it becomes possible to reduce unnecessary operations of a developing device and a photosensitive drum and extend a usable life of the developing device even if image formation and temperature rising of the fixing device are performed in parallel.

    摘要： An image forming apparatus includes an image bearing member for bearing an electrostatic image, a plurality of developing units for accommodating developers having different colors, a light source for projecting light onto a developed image, and a photosensor for sensing reflected light from the developed image. The apparatus operates in either a first mode for determining the density of the developed image based on the output of the photosensor when light having a predetermined amount is projected from the light source, or in a second mode for determining the density of the developed image based on the amount of light projected from the light source when the output of the photosensor has a predetermined value. Either the first mode or the second mode is selected in accordance with the color of a developer being utilized during the image formation operation.
