Toner particles fly off from a photosensitive drum to an exposure light emitting portion by a change of electric potential distribution on the photosensitive drum caused by image exposure in a following process. This causes a poor copy of an image by adhering the toner particles to the exposure light emitting portion. This phenomena affects a tandem type of copiers with multi-stations including photosensitive drums and exposure light emitting positions. An apparatus capable of suppressing toner adhesion to an exposure is provided to solve the above problem.

An image forming apparatus includes an image bearing member; a charging member, contactable to said image bearing member, for being supplied with a voltage to charge said image bearing member; a developing device for forming a toner image by developing with toner an electrostatic image formed on said image bearing member, and also being capable of cleaning said image bearing member to remove residual toner; and a transferring device for transferring the toner image onto a transfer material. When the apparatus stops during an image forming operation as during a jam, the voltage applied to said charging member is a superimposed voltage of an AC voltage and DC voltage and is a DC voltage without the AC voltage thereafter between resumption after jamming and the start of image formation.

A color image reading apparatus includes a plurality of line sensors which have different color filters and each of which has a plurality of light receiving elements. One of the plurality of line sensors has an opening width larger than those of the remaining line sensors. The apparatus also includes a correcting unit such as an edge emphasis circuit for correcting image signals output from the line sensors so as to obtain identical resolutions of the image signals, and a processing unit such as a masking circuit for performing color processing of the image signals corrected by the correcting unit.

The resistivities of a transfer material or a transfer material carrying sheet change depending on the variation in the ambient conditions, the materials of the transfer material and the charge-up of the transfer material carrying sheet. Therefore, even if the charging by the transfer charger is maintained constant, the image transfer operation is not stable. An image transfer apparatus in which the charging amount by the transfer charger is controlled in accordance with the resistivities to stabilize the image transfer operation is disclosed The transfer charger will be controlled in accordance with an electric current flowing through a contact member when a transfer material passes between the contact member and a transfer material carrying sheet.

After a first image is formed on an image bearing member, the potential of the image bearing member is attenuated, and then, the image bearing member is re-charged. Thereafter, a second image is formed. The image forming apparatus includes a potential sensor for detecting the surface potential of the image bearing member, and in accordance with the output of the potential sensor, amount of potential attenuation and/or amount of re-charging is controlled so that the potential difference between the potential of the first developed portion after the re-charging and the background potential is converged into a predetermined target range.

Fiber-treating compositions are described which durably provide water repellency and oil repellency for the treated fibers. These compositions comprise a cyclic siloxane bearing fluorinated hydrocarbon radicals and silicon-hydride atoms, and a dehydrogenation catalyst. Curing of the compositions occurs by a dehydrogenation condensation reaction between the silicon-hydride atoms and/or between the silicon-hydride atoms and the hydroxyl radicals of an optionally added hydroxyl-endblocked organopolysiloxane.

An information processing system and an electronic message notification method for an information processing system automatically change an incoming account for which an electronic message reception notification is made. An information processing system includes an information terminal provided with a communication function and an in-vehicle device. The information terminal receives an electronic message from the exterior in a corresponding incoming account; configures an incoming account for making a notification of the reception of an electronic message; and when an electronic message has been received by the configured incoming account, notifies the in-vehicle device. The in-vehicle device determines whether or not an electronic message has been distributed to the information terminal from a specific partner; and, if so, changes the configuration of the configuration unit so that a notification that the electronic message has been received from the specific partner is made.

A navigation apparatus and route search method by which a roundabout route is avoided even if there is a segment with a regulation such as “no left turn” or “no entrance” are disclosed.The route search method for a navigation apparatus by which a route to a destination defined by a predetermined segment having its endpoint at an intersection is searched in the case where a destination or a stopover point is the intersection. In the case where the destination or the stopover point is an intersection CP, route search is performed in accordance with each segment SEG1 to SEG4 having their endpoint at the intersection CP searched as a destination segment. An optimal route (for example, the shortest route) is selected from among the searched routes, and the optimal route is determined to be a guide route to the destination or the stopover point.

A navigation system provides guidance for performing a U-turn. The navigation system includes a processing unit, which acquires guidance route information and road information to determine whether the guidance route requires a turning around in a divided two-lane road. If a turning around is required, the processing unit specifies an extension distance of a connection road of the divided two-lane road. U-turn guidance is provided if the extension distance is at or below a predetermined length, or otherwise, to guidance is provided to prompt a double turn.
