Abstract: An electrophotographic image forming apparatus including an absolute humidity derivation section which derives absolute humidity inside the apparatus, and a control section which, when the absolute humidity inside the apparatus derived by the absolute humidity derivation section is smaller than a predetermined first threshold value, sets a dither pattern density based on an original image to be smaller compared to when the absolute humidity inside the apparatus is larger than the predetermined first threshold value, and forms a latent image on a photosensitive drum.

Abstract: A print sheet creation method, including a first transfer step of forming a laminated film by transferring a first toner layer including achromatic toner and a second toner layer including chromatic toner and formed on the first toner layer to a first transfer target medium, a second transfer step of transferring the formed laminated film to a second transfer target medium from the first transfer target medium such that the first toner layer is an uppermost layer, a first fixing step of fixing the laminated film transferred to the second transfer target medium to the second transfer target medium, and a third transfer step of transferring a third toner layer which includes achromatic toner and is thicker than the first toner layer to the laminated film fixed to the second transfer target medium and having the first toner layer as the uppermost layer.

Abstract: A vacuum processing apparatus includes a process chamber; a transport unit for transporting a plurality of substrates; a gas supply unit; a substrate processing unit for processing the substrates placed on the transport unit; a detection unit for detecting a substrate interval between adjacent substrates out of the plurality of substrates; and a control unit for controlling, based on the substrate interval detected by the detection unit, a supply amount of the gas to be supplied by the gas supply unit.

Abstract: In an image forming apparatus provided with a detachable fixing unit having fixing paired-rollers, a heating unit heats at least one of the fixing paired-rollers, and a temperature detecting unit detects a temperature of the detachable fixing unit. The image forming apparatus is further provided with an adjustment mechanism for preventing the detachable fixing unit from being taken out from the apparatus body, when the temperature detecting unit determines that the temperature of the detachable fixing unit exceeds a predetermined value, and allowing the detachable fixing unit to be taken out from the apparatus body, when the temperature detecting unit determines that the temperature of the detachable fixing unit is the predetermined value or less, whereby protecting users from getting their hands burned when taking out the detachable fixing unit from the apparatus body.

Abstract: A vacuum processing apparatus includes: a process chamber capable of reducing a pressure; a transport unit, provided in the process chamber, for transporting a plurality of substrates; a gas supply unit for supplying a gas to process the substrates in the process chamber; a substrate processing unit for processing the substrates placed on the transport unit; a detection unit for detecting a substrate interval between adjacent substrates out of the plurality of substrates; and a control unit for controlling, based on the substrate interval detected by the detection unit, a supply amount of the gas to be supplied by the gas supply unit.

Abstract: An upper body which can be shifted from and toward a lower body through a link mechanism is formed. A drum unit and a toner unit are arranged on the side of the upper body. The upper body is opened in the parallel with respect to the lower body with a predetermined interval, by the link mechanism including arms. In the state where the upper body is opened, the drum unit and the toner unit can be detached from and attached to the printer device in frontward and backward directions, by sliding a sliding member arranged on the upper body.

Abstract: When, in a two-color image forming apparatus, a first visible image is formed on a photosensitive drum, and sequentially a second visible image is formed on the drum on which the first visible image remains, said second visible image being different in color from said second visible image, a cylindrical non-magnetic sleeve rotates in a direction opposite to a rotation of a permanent magnet equipped with the sleeve, thereby enabling a developer to be conveyed in a direction opposite to a rotation of the permanent magnet.
