摘要： An image forming apparatus includes an endless belt stretched over a plurality of rollers. The apparatus also includes a potential detecting device for detecting a potential of the endless belt. The detecting device is positioned downstream, along a sheet transport path, of a transfer position where the belt has direct contact with the image bearing member. The apparatus further includes a transferring member for transferring a toner image formed on the image bearing member to a sheet. An image forming process is halted when the potential detecting device does not detect a change in potential caused by presence of a sheet on the endless belt.

摘要： Transfer roller(s) is/are such that either end thereof is formed from fibrous electrically conductive component(s) and such that cylindrical portion(s) in central region(s) is/are, for example, formed from metal roller-like structure(s), either fibrous electrically conductive component outer end being arranged so as to extend somewhat beyond either transfer/transport belt side. Furthermore, outside diameter(s) approximated by tips of respective individual fiber(s) of fibrous electrically conductive component(s) is/are somewhat larger than diameter(s) of metal roller-like structure(s). This makes it possible for electric field(s) to be applied, and for charging to occur, along the full width(s) of transfer/transport belt(s).

摘要： A timer clocks and accumulates time periods during each of which a recording sheet is transported or transfer bias is applied as transfer execution periods. When the accumulated value reaches a predetermined value, the timer outputs a time-up signal to a CPU and then clears the accumulated value. The CPU executes a cleaning operation at the time the time-up signal is inputted from the timer. In the cleaning operation, the CPU causes a high-voltage power source to apply cleaning bias to a transfer electrode roller while causing a high-voltage power source to apply delivery bias to an auxiliary cleaning roller, in order to return toner attracted to the auxiliary cleaning roller to a photosensitive drum via a transfer belt.

摘要： A solid-state imaging device includes: photoelectric conversion elements disposed on an imaging surface of a substrate, receiving light incident on a light receiving surface and performing photoelectric conversion to produce a signal charge; electrodes interposed between the photoelectric conversion elements; and light blocking portions provided above the electrodes and interposed between the photoelectric conversion elements. The light blocking portions include an electrode light blocking portion formed to cover the corresponding electrode, and a pixel isolation and light blocking portion protruding convexly from the upper surface of the electrode light blocking portion. The photoelectric conversion elements are arranged at first pitches on the imaging surface. The electrode light blocking portions and the pixel isolation and light blocking portions in the light blocking portions are arranged at second and third pitches, respectively, on the imaging surface. At least the third pitch increases with distance from the center toward the periphery of the imaging surface.

摘要： The present invention is made to provide a pretransfer charging device, which allows (i) reduction of generation of discharge products such as ozone and nitroxide, (ii) excellent uniform charging, (iii) continuous stable charging for a long period of time, and (iv) restraint of distortion of a toner image. The pretransfer charging device includes (i) ion generation needles each provided face to face with an image carrier such as a photoconductor drum or an intermediating transfer belt, and (ii) a high-voltage power supply for applying a negative voltage to each of the ion generation needles. The voltage to be applied from the high-voltage power supply is not less than an ion production threshold voltage but is less than a corona discharge threshold voltage. With this, no corona discharge occurs but negative ions can be generated. This makes it possible to solve various problems caused due to the corona discharge.
