Abstract: An image forming apparatus includes a belt member, a secondary transfer member which is abutted against the belt member to secondary transfer a toner image to a recording medium and a contact/separation mechanism which brings the secondary transfer member into contact with a first widthwise end portion in the belt member first.

Abstract: A belt member is seamed to form an endless belt which is stretched by a plurality of roller members and circulated in a first direction. The belt member is provided with an electrode portion at a first end portion thereof in a second direction perpendicular to the first direction. A cleaning member is abutted against the belt member. A seam of the belt member extends obliquely relative to the first direction such that an end of the seam confronting the electrode portion is situated in an upstream side of the first direction.

Abstract: An intermediate transfer belt having a plurality of layers including a conductive layer, and having a transfer area and a transfer protection area. A CPU sends a control signal to a primary transfer bias generating circuit, and applies a primary transfer bias upon the conductive layer of the intermediate transfer medium through a bias applying member. The CPU changes an output value of the primary transfer bias in accordance with a predetermined bias change condition when a secondary transfer is not ongoing and when a non-image area, in which there is no toner image transferred on the intermediate transfer belt, such as the transfer protection area is passing the primary transfer part.

Abstract: A tire inflation pressure monitoring device includes transmitters for transmitting air pressure signals indicative of air pressures in tires, detected by respective air pressure sensors, and a receiver for generating a warning signal in accordance with the air pressure signals received from the transmitters. The air pressure signal transmitted from each of the transmitters includes an ID of the corresponding transmitter as an ID signal. When the receiver is in an ID registration mode in which the IDs of the transmitters are registered (S12), the transmitters are forced to transmit the air pressure signals, and if the number of the received air pressure signals is equal to a predetermined value, the receiver registers the IDs of the transmitters based on the ID signals included in the received air pressure signals (S20, S26).

Abstract: When an alarm switch of a transmitter is given a long press carried out for one or more seconds in a timer-reset condition, a first alarm reversal signal is transmitted simultaneously with the setting (starting) of the timer. If the alarm switch is pressed within the set time of the timer regardless of a press time period, a second alarm reversal signal is transmitted, and the timer is reset. On a receiver side, the activation and deactivation of the alarm is alternately performed upon receipt of each alarm reversal signal.

Abstract: A recording medium carrier system of an image forming apparatus is constituted by independent units as a paper supply cassette, a paper feed unit, a transfer unit, a fixing unit, and a paper ejecting unit. An intermediate transfer unit in the transfer unit is provided with an intermediate transfer belt to which a toner image formed on a photoconductive drum is primarily transferred at a primary transfer position and which secondarily transfers the toner image on a recording medium at a secondary transfer position, and a driving roller for circulating the intermediate transfer belt. The primary transfer position is arranged close to the driving roller.

Abstract: To issue a warning against an improper (a lowered) air pressure in accordance with a vehicle state and driver's presence/absence, the warning system includes air pressure measuring means for measuring an air pressure of a tire of a vehicle; air pressure judging means for judging whether or not the air pressure is proper; warning issuing means for issuing, if a result of the judgment is negative, a warning; and driver on-board judging means for judging whether or not a driver is on board the vehicle; and driver detecting means for detecting whether or not the driver is in the proximity to the vehicle. If the results of the judgments by the air pressure judging means and the driver on-board judging means are negative and a result of the detection by the driver detecting means is positive, the warning issuing means issues the warning outside the vehicle.

Abstract: A transfer device includes a pair of transfer frames, a belt member, a pair of transfer roller levers which are respectively arranged on inner sides of the transfer frames pivotably, a transfer roller which is provided between first ends of the transfer roller levers rotatably, a pair of first urging members, which are respectively provided on second ends of the transfer roller levers to energize the transfer roller toward the belt member, and a pair of transfer pressure controlling members which are respectively provided on the transfer frames movably to control urging power of the first urging members.

Abstract: An intermediate transfer belt comprises a plurality of layers including a conductive layer, and has a transfer area and a transfer protection area. A CPU 111 sends a control signal to a primary transfer bias generating circuit 116, and applies a primary transfer bias upon the conductive layer of the intermediate transfer medium through a bias applying member 31A. The CPU 111 changes an output value of the primary transfer bias in accordance with a predetermined bias change condition when secondary transfer is not ongoing and when a non-image area, in which there is no toner image transferred on the intermediate transfer belt, such as the transfer protection area is passing the primary transfer part.
