摘要： An image forming apparatus includes an image carrier that carries a toner image; a transfer member that forms a transfer nip between the transfer member and the image carrier; and a power supply capable of outputting a superimposed transfer bias in which an alternating current component is superimposed onto a direct current component. The toner image on the image carrier is transferred onto a recording medium in the transfer nip by the superimposed transfer bias or a direct current bias consisting of the direct current component output by the power supply. The apparatus also includes a controller that controls the power supply so that an output target value of the direct current component when the direct current component rises up is larger than an output target value of the direct current component when the toner image is transferred onto the recording medium.

摘要： An image forming apparatus includes an image bearer; a toner image forming unit, a transfer unit, a detector, and a controller. The toner image forming unit forms a plurality of types of density detection patterns on the surface of the image bearer in mutually-different positions in a surface-movement direction of the image bearer. The density detection patterns have mutually-different lengths in a direction orthogonal to the surface-movement direction of the image bearer. The transfer unit transfers the density detection patterns onto the surface of the transfer member. The detector detects image densities of the density detection patterns transferred on the surface of the transfer member. The controller calculates an image density difference between the density detection patterns on a basis of a detection result obtained by the detector, and corrects a transfer bias for transferring a toner image on a basis of a value of the image density difference.

摘要： For establishing a VPN connection in the call-back type, a VPN server establishes an always-on connection through a unique protocol different from the electronic mail delivery system. A client generates a client authentication data used for the client authentication implemented by the VPN server, and establishes the relay server through the unique protocol to transmit the client authentication data. The relay server device relays the client authentication data to the VPN server through the unique protocol. The VPN server implements the client authentication based on the relayed data. The VPN server establishes the VPN connection with the client based on the result of the authentication.

摘要： In a transfer-fixing device for transferring and fixing a toner image on a transfer-fixing side of a recording medium, a transfer-fixing member carries the toner image. A pressing member presses against the transfer-fixing member to form a nip between the transfer-fixing member and the pressing member through which the recording medium passes. A heat transmission member is provided upstream from the nip in a recording medium conveyance direction to heat the transfer-fixing side of the recording medium while guiding the recording medium to the nip. A heating member is connected to the heat transmission member to heat the heat transmission member. A biasing member biases the recording medium guided by the heat transmission member against the heat transmission member.

摘要： A medium management method is disclosed. A removable medium is conveyed to a drive section when the removable medium is inserted into a medium accommodation section. The drive section reproduces and reads information from the medium and determines whether the medium is a first medium or a second medium on which data externally or internally created have been recorded according to the information read by the drive section. A partial reproduction operation is performed according to an edit list recorded on the first medium and the reproduced data are transferred to a pre-designated host system when the inserted medium is the first medium. The second medium is registered to a database when the determined result denotes that the inserted medium is the second medium. The medium is returned to the medium accommodation section after one of the partial reproduction operation and the database registration process has been completed.
