摘要： An image forming apparatus includes a reference-pattern detecting transfer-body, a reference-pattern detecting unit, and a condition changing unit. The reference-pattern detecting transfer-body directly transfers a reference pattern image formed on an intermediate transfer body without a recording material. The reference-pattern detecting unit detects an optical reference pattern with respect to the image transferred onto the reference-pattern detecting transfer-body. The condition changing unit changes the image forming conditions based on a result of detection.

摘要： A color image forming apparatus includes a plurality of image forming sections independent of each other. The image forming sections store respective toner of different colors that are chargeable to the same polarity. All the toner are implemented by the same binder resin and provided with the same particle size distribution. Further, developing units each storing toner of particular color are identical in specification. When two-ingredient type developers are used, the developers contain an identical carrier. The apparatus recycles the toner of different colors to the respective developing units. The alien color toner collected in each developing unit is prevented from remaining by being chargeable to the same polarity.

摘要： An electrophotographic image forming apparatus including an LED (Light Emitting Diode) array head and a method of generating data for correcting the quantities of light to issue form the LEDs of the LED array head are disclosed. Only the quantity of light that actually contributes to development is uniformed throughout the LEDs. This reduces the scatter of a dot area in a latent image and thereby enhances image quality while insuring the sufficient resolution of the LEDs.

摘要： An image forming apparatus includes an image carrier, a toner-image forming unit, a photosensor, an information obtaining unit, and a toner-amount calculating unit. The toner-image forming unit forms a toner image on the image carrier with toner. The photosensor detects a toner area where the toner is sticking to the image carrier. The information obtaining unit obtains particle-size-change information about how particle size distribution of the toner changes over time. The toner-amount calculating unit calculates a toner amount of the toner image based on the toner area and the particle-size-change information.

摘要： Toner images of different colors are superimposed on a transfer belt of an endless type from image carriers, to form a full color toner image. A tension roller maintains a tension of the transfer belt. A driving roller drives the transfer belt. A biasing unit applies the tension to the tension roller. A holding unit holds the tension roller. An image reading sensor detects the toner image formed on the transfer belt. The image reading sensor is disposed in the holding unit, in an opposite position to the tension roller with respect to the transfer belt.

摘要： A method for evaluating an electric resistance member of an image forming apparatus which can maintain good image quality, without the occurrence of transfer defects such as insufficient transfer, even in a long-term use. An intermediate transfer belt of the image forming apparatus, which is evaluated based on a fluctuation characteristic of the resistivity in a period of continuous voltage application, is used. The absolute value Δρs of the amount of changes in the surface resistivity of the intermediate transfer belt within 2 seconds to 100 seconds from the beginning of voltage application is 0.3 [Log(Ω/)] or less, when the surface resistivity ρs is measured by applying a voltage of 500 V. The absolute value Δρv of the amount of changes in the volume resistivity within 2 seconds to 100 seconds from the beginning of voltage application is 0.5 [Log(Ω·cm)] or less, when the volume resistivity ρv is measured by applying a voltage of 200 V.

摘要： An electrophotographic color image forming apparatus of the present invention includes a plurality of image forming sections each including an image carrier and image transferring means. Toner images of different colors are sequentially transferred from the image carriers to a sheet being conveyed by an endless belt while electrostatically adhering to the belt, completing a color toner image. Assuming that the surface of each image carrier and that of the belt move at speeds of Vd and Vb, respectively, a ratio of Vb/Vd can be varied by the user of the apparatus. In addition, assuming that a surface of an intermediate transferring mechanism and a surface of a recording medium move at speeds of Vp and Vi, respectively, the ratio of Vp/Vi can be varied by the user.
