    摘要: In order to achieve such effects that memories such as image memory due to untransferred residual toner can be sufficiently prevented, and good images can be obtained by suppressing base fogging and reduction of entire image density for a long term, an oscillating voltage composed of a DC ingredient and an oscillating ingredient is applied to a charging device for charging a photosensitive member, while the charging device is in a position facing an image forming region of the photosensitive member. While the charging device is in a position facing an image non-forming region of the photosensitive member, only a DC voltage is applied to the charging device for at least a predetermined time.

    摘要: Face detection is executed only on an image imaged based on an arbitrary (predetermined) focal point information defined in advance. In face detection, the face of a person is detected based on a relative value of statistics in a plurality of characteristic regions produced by contour or parts of the face of the person. Thus, even if the face in the image used for face detection is blurred, the statistics in a certain region can be acquired, and thus such face is detectable. Therefore, the primary subject to be focused can be rapidly detected without performing focal point control at a stage of preliminary imaging in the imaging apparatus.

    摘要: A washer-dryer apparatus has a blower for sucking air from a water tank and blowing the air into a washing and dewatering tub. At an inlet of the blower is provided a filter, which is cleaned by a cleaning device (300). The cleaning device (300) has a main body (301) pivotable about one end thereof relative to an outer bottom surface of the water tank, a brush (302) provided on the other end of the main body, and a bias spring (303) for biasing the main body toward an opening direction. The main body (301) is subjected to a dynamic pressure of water in the water tank and thereby pivots in an opening direction. When the main body (301) has the pivoting angle of 90°, the brush (302) is in contact with the filter.
