摘要： An image forming apparatus includes a toner carrier, a toner image forming unit, and a toner concentration sensor. The toner carrier includes a transparent film. The toner image forming unit forms a toner image onto the toner carrier. The toner concentration sensor senses the concentration of toner on the toner carrier. The toner concentration sensor includes first and second light emitting elements and a light receiving element. The light emitting elements each radiate light directly or indirectly to the toner carrier. The light receiving element receives reflecting light originating from the light emitting elements. The first light emitting element radiates light having a wavelength of a predetermined reflectance resulting from direct radiation to the toner carrier. The second light emitting element radiates light having a wavelength that causes a lower reflectance resulting from direct radiation to the toner carrier than a reflectance resulting from radiation to the toner.

摘要： An image forming apparatus has a moving part that operates for forming an image on recording paper. When an instruction to make a transition to a silent mode is input to an input unit, first control is executed so that operation noise of the moving part is reduced. When an instruction to cancel the silent mode is input to the input unit, second control is executed so that the operation noise of the moving part is increased stepwise to return to the state before the first control.

摘要： An image forming apparatus calculates a positional deviation in the main and sub-scanning directions for each color by forming registration patterns in two arrays along a sub-scanning direction on an image carrier. Each registration pattern in one array is paired with an identical registration pattern in the other array. A first sensor has: a light-emitting element irradiating one registration pattern in a pair; a photodetector for regular reflection light; and a photodetector for diffuse reflection light. A second sensor has: a light-emitting element irradiating the other one in the pair; and a photodetector for regular reflection light. The relative positions of a pair of registration patters calculated using the respective sensors are corrected so as to reduce the positional deviation between the calculated positions by the amount of offset deviation estimated occur between positions detected by the respective sensors when the registration patterns are without positional deviation.

摘要： An image forming apparatus outputting a color image and a monochrome image obtains data for output image by RIP-convert of accepted image data, and extracts feature of the data for output image. When the data for output image is determined to correspond to a color image, the image forming apparatus outputs a color image corresponding to the data for output image, on condition that the feature satisfies a determination reference.
