Abstract:
A developing device includes a first developing roller including a first transport member that transports magnetic developer by rotating while being close to a latent-image carrier rotating in one direction and a first magnet member, a second developing roller including a second transport member that transports the developer by rotating while being close to the latent-image carrier at a position on a downstream side of the first developing roller in the one direction, and a second magnet member, and a regulation member that regulates transport amounts of the developer distributed to the first and second developing rollers to required transport amounts, and opposes the developing rollers with predetermined distances therebetween. The first and second developing rollers are spaced from each other. The regulation member is movably supported in an area closer to the latent-image carrier than a closest position between the first and second developing rollers.

A headrest (7) is mounted to a seat back (3) and movable forward from a set position, a linking mechanism (19) is provided on the seat back (3) for transmitting an inertial force due to the load by a passenger's body acting on the seat back (3), causing the headrest (7) to move forward, a detector (21) performs a detection of contact of the passenger'body with the headrest (7), and a canceler (23) cancels transmission of the inertial force by the linking mechanism (19) when contact of the passenger's body with the headrest (7) is detected by the detector (21).
Abstract:
An LED array head has LED arrays, a substrate, first electrode pads, second electrode pads, and light-blocking elements. Plural LEDs are positioned at the LED arrays. The LED arrays are staggered on the substrate. The first electrode pads are provided at end portions of the LED arrays and positioned facing LEDs of adjacent LED arrays. The second electrode pads are provided on the substrate at a side opposite the adjacent LED arrays and connected to the first electrode pad electrically by the wires. The light-blocking elements block light, which is emitted from the LEDs of the adjacent LED arrays, from reaching the wires.

Abstract:
A developing device includes first and second developer carriers facing each other in a facing region, a regulating member that regulates a layer thickness of developer, and a separation member. The first and second developer carriers respectively include first and second magnetic members that are respectively magnetized with first and second facing magnetic poles having opposite polarities. The separation member separates the developer so that the developer is supplied toward the first and second developer carriers. The separation member is disposed such that distances between the separation member and the first and second developer carriers are the smallest in a region in which a magnitude of a combined magnetic field of the first and second magnetic poles locally decreases as compared with a case where at least one of the first and second developer carriers is independently disposed due to interaction between the first and second facing magnetic poles.
