| Application No. | Application Title | Issue Date |
| 20080063421 | IMAGE FORMING APPARATUS An image forming apparatus includes a first image forming station for forming, on the basis of an input signal indicative of an image, a toner image on a recording material with such a toner of toners having the same hue and different lightness as has a predetermined co... | 03/13/2008 |
| 20080056752 | Multipath Toner Patch Sensor for Use in an Image Forming Device A toner patch sensor for use in an image forming device may be operated in different modes according to the color of the patch being sensed. The toner patch sensor may include a detector and a source adapted to transmit light that is reflected off a toner patch and towa... | 03/06/2008 |
| 20070292156 | IMAGE FORMING APPARATUS AND IMAGE PROCESSING METHOD An image forming apparatus comprises an operation unit which performs an operation for calculating amount data of a printing material which indicates an amount of a printing material required to form the image, a reduction processing unit which changes, when it is deter... | 12/20/2007 |
| 20070223954 | TONER DENSITY DETECTION APPARATUS AND IMAGE FORMING APPARATUS HAVING THE SAME A toner density detection apparatus has a sensor unit and a controller. The sensor unit irradiates a toner patch formed on an image carrier with light, splits the light reflected by the toner patch into first and second light components, receives the first and second li... | 09/27/2007 |
| 20070223946 | METHOD AND APPARATUS FOR IMAGE FORMING CAPABLE OF CONTROLLING TONER CONCENTRATION ACCURATELY A toner-concentration controller includes a controller configured to control a toner supply amount in accordance with a detection result of a toner-concentration of two-component toner, and a sensor unit configured to detect the toner-concentration of two-component tone... | 09/27/2007 |
| 20060228124 | Image-forming device and transfer device A blocking disk formed with a notched part is disposed between a density sensor and a belt. The exposure/blocking of the density sensor relative to the belt is switched by rotating the blocking disk. In one example, a disk-supporting axel gear is formed on a disk-suppor... | 10/12/2006 |
| 20060204267 | Image forming apparatus A toner density on a toner image carrier means such as an intermediate transfer belt is accurately measured, even if a durability of the toner image carrier means is changed. It is assumed that output dark voltages from said first and second photo-detector means are P0 ... | 09/14/2006 |
| 20060104654 | METHOD AND APPARATUS FOR MEASURING TONER CONCENTRATION A device to measure toner concentration can include a selector that selects a type of developer material to be measured and a sensor that detects an amount of light reflected off a developer material. A controller within the device can determine a value corresponding to... | 05/18/2006 |
| 20060024077 | Method and system for calibrating a reflection infrared densitometer in a digital image reproduction machine An enhanced toner area coverage (ETAC) sensor may be calibrated to adjust for changes in LED intensity by determining a functional relationship between specular developed mass per unit area (DMA) values and diffuse readings obtained from the sensor. Specular and diffuse... | 02/02/2006 |
| 20050214015 | Densitometer for use in a printer A method and apparatus for a densitometer comprising a multicolor LED having a light adjustment mechanism for controlling the amount of light received by a light detector in the densitometer. The MCLED is comprised of a plurality of different color LEDs and a controller... | 09/29/2005 |
| 20050105926 | Electrophotographic apparatus An image detector has an I/V converter for converting, into a voltage output., a current output as a result of a photoelectric element arranged in a traveling direction of an intermediate transfer belt having received light reflected from the intermediate transfer belt ... | 05/19/2005 |
