摘要： An image forming apparatus includes an image carrying member to carry a toner image, a nip forming member to form a transfer nip with the image carrying member, and a transfer bias outputting unit to output a transfer bias to transfer the toner image from the image carrying member to a recording medium. The transfer bias is composed of a direct current (DC) component and an alternating current (AC) component, and a least one of the DC component and the AC component is subjected to constant voltage control. When constant current control is conducted at a timing other than when the toner image is being transferred from the image carrying member to the recording medium, a detection bias voltage at the transfer nip is detected, and the voltage of at least one of the DC component and the AC component is controlled based on the detected detection bias voltage.

摘要： An image forming apparatus includes a transfer member configured to abut against an image carrier for carrying a toner image to form a transfer nip; and a power supply configured to output a bias voltage for transferring the toner image on the image carrier onto a recording medium nipped in the transfer nip. The bias voltage includes a first voltage for transferring the toner image from the image carrier onto the recording medium in a transfer direction and a second voltage having an opposite polarity of the first voltage, the first and the second voltages being alternately output. A time-averaged value of the bias voltage is set to a polarity in the transfer direction and is set in the transfer direction side with respect to a median between a maximum and a minimum of the bias voltage.

摘要： Positional relationships are automatically determined with higher accuracy in a predetermined direction between three-dimensional images representing a subject including a periodic structure having periodicity in the predetermined direction, with respect to the periodic structure. A positional correspondence is provisionally determined in a predetermined direction between two three-dimensional images including a periodic structure having periodicity in the predetermined direction, based on a criterion wherein the periodic structure contributes less to the determination. The provisionally determined correspondence is then corrected so that a position in one of the three-dimensional images corresponding to a position of the other three-dimensional image in the predetermined direction can be corrected within a range near the position in the former three-dimensional image in the predetermined direction, according to a criterion wherein the periodic structure contributes more.

摘要： When an image group to be displayed and compared is transferred to a terminal during viewing and processing of an image in an image group on the terminal that enables viewing of a plurality of image groups, an image corresponding to the currently displayed image is promptly transferred and displayed. In response to determination of the image group to be displayed and compared with the image group currently displayed on the terminal, a server determines the image that belongs to the image group to be displayed and compared and corresponds to the image in the image group being displayed, and determines a range and order of transfer of images that are to be transferred and include the corresponding image in the determined image group. The server transfers the determined image group according to the range and order of transfer.
