Abstract: A seat back panel includes a panel main body and a separate panel. The panel main body is disposed at a posterior portion of a seat back of a vehicle seat. The panel main body structures a portion of a main body portion of a seat back frame. An aperture is formed at a location of the panel main body that opposes a dorsal region of a seat occupant. The separate panel is attached to the main body portion and closes up the aperture. At a time of rear-end collision of the vehicle, the separate panel receives a load from the dorsal region of the seat occupant and relatively displaces toward the rear side of the seat back with respect to the panel main body.

Abstract: An image forming apparatus includes circuitry, a reader, and an exposure device that drives lighting elements aligned in a main scanning direction to form a first test image. The circuitry acquires density of first sub-areas, into which the first test image is divided in the main scanning direction, and calculates first correction data based on density of each of the first sub-areas and average density of the first sub-areas, to correct light amounts of the lighting elements. The exposure device forms a second test image with the light amounts corrected. The circuitry acquires density of second sub-areas, into which the second test image is divided in the main scanning direction, and calculates second correction data based on density of a second sub-area adjacent to each of the second sub-areas, to further correct the light amounts. The second sub-areas are differently located from the first sub-areas in the main scanning direction.

Abstract: An image forming apparatus includes a latent image bearer, a latent image writing device, a developing device, a conveyance unit to convey a recording medium, a transfer device, a length data acquisition unit to obtain a length of the recording medium in a conveyance direction of the recording medium, an image forming processor to form a test pattern, and a light quantity correction calculator that acquires image density data of the test pattern and calculates a light quantity correction value to correct a light quantity. The image forming processor sets a position of the test pattern on the recording medium in the conveyance direction of the recording medium and a length of the test pattern in the conveyance direction of the recording medium based on the length of the recording medium in the conveyance direction of the recording medium obtained by the length data acquisition unit.

Abstract: A scanner includes: an acquiring unit that acquires determination result information based on a determination result of whether a target dot of a target pixel of a plurality of pixels constituting image data is a first dot or a second dot; a light source control unit that, if the target dot is the first dot, causes a light source to emit a light beam during a corrected lighting time with a light source characteristic time based on a characteristic of the light source being added to a predetermined lighting time that is preliminarily determined with respect to the target dot, and if the target dot is the second dot, causes the light source to emit a light beam during the predetermined lighting time; and a deflecting unit that deflects the light beam in the main scanning direction.

Abstract: An image-forming apparatus includes a first opened/closed signal generation unit for generating a first opened/closed signal indicating an opened/closed state of the open/close member by using polling detection; a second opened/closed signal generation unit for generating a second opened/closed signal in which a state indicating the opened state of the open/close member is latched when a second signal via the switch is cut off; and a power-supply failure detection unit for detecting a power-supply failure based on the first and/or second opened/closed signals.
