摘要： An image forming apparatus includes a color toner image forming device, a fixing device, a cooling device, a colorless toner image forming device, and a control device. The color toner image forming device forms a toner image on a recording medium with a color toner. The fixing device heats the toner image on the recording medium to fix the toner image on the recording medium. The cooling device cools the fixed toner image. The colorless toner image forming device forms a toner image on the recording medium with a colorless toner having a storage elastic modulus of 100 or less and a loss tangent of 10 or greater at a heating temperature of the fixing device. The control device controls cooling power of the cooling device based on whether or not the colorless toner image forming device forms the toner image.

摘要： An image forming apparatus includes a latent image bearer; a developing device containing two-component developer and including a developer bearer, a development voltage source, and a toner concentration detector; a toner supply device to supply toner to the developing device; a transfer device; and a controller to keep a toner concentration in the developer in the developing device at a target toner concentration during image formation. The controller executes forced toner consumption in which the developing device supplies the toner to the latent image bearer the toner at a predetermined forced toner consumption timing, while inhibiting the toner supply device from supplying toner. When the toner concentration falls to a prescribed toner density lower than the target toner concentration, the controller completes the forced toner consumption and executes a post-consumption toner supply operation.

摘要： An image forming apparatus includes a toner pattern bearer to bear a first toner pattern having a first image area rate and a second toner pattern having a second image area rate different from the first image area rate. A toner adhesion amount detector detects a toner adhesion amount of toner of each of the first toner pattern and the second toner pattern. A toner degradation rate calculator calculates a first deviation in the toner adhesion amount of the first toner pattern and a second deviation in the toner adhesion amount of the second toner pattern based on the toner adhesion amount detected by the toner adhesion amount detector. The toner degradation rate calculator compares the first deviation with the second deviation and calculates a toner degradation rate based on a comparison result.

摘要： An image forming apparatus includes an image bearer, a toner image forming device, a plurality of image density detectors, and a controller. The plurality of image density detectors are disposed at predetermined intervals opposite the image bearer in a width direction of the image bearer. The controller causes the toner image forming device to form toner image patterns having an identical density at the plurality of positions on the image bearer and the plurality of image density detectors detects a density of the toner image patterns. Based on the detected density of the toner image patterns, the controller identifies multiple cyclic fluctuations of the density of the toner image patterns and adjusts an image forming condition based on the multiple cyclic fluctuations of the density of the toner image patterns to decrease an amplitude caused by the multiple cyclic fluctuations of the density of the toner image patterns.

摘要： A device that estimates carrier deterioration indicating a degree of deterioration of carrier inside a developing device using a two-component developer includes a first carrier deterioration calculation unit, a second carrier deterioration calculation unit, and a carrier deterioration degree output unit. The first carrier deterioration calculation unit uses toner consumption and agitation time to calculate a first carrier deterioration degree indicating a degree of carrier deterioration caused by a spent phenomenon. The second carrier deterioration calculation unit uses the toner consumption and the agitation time to calculate a second carrier deterioration degree indicating a degree of carrier deterioration caused by a carrier abrasion phenomenon. The carrier deterioration degree output unit uses the toner consumption to select one of the first carrier deterioration degree and the second carrier deterioration degree, and outputs the selected carrier deterioration degree.
