    Abstract: An image forming apparatus includes an image forming portion, a first acquisition processing portion, a second acquisition processing portion, and an adjustment processing portion. The image forming portion forms an image on a sheet. The first acquisition processing portion acquires a captured image of the sheet. The second acquisition processing portion acquires a specific value that indicates a difference between a gradation value of a pixel that, among pixels included in the captured image acquired by the first acquisition processing portion, corresponds to a higher part of an outer surface of the sheet, and a gradation value of a pixel that, among the pixels included in the captured image, corresponds to a lower part that is lower than the higher part. The adjustment processing portion adjusts an image forming condition of the image forming portion based on the specific value acquired by the second acquisition processing portion.

    Abstract: A fixing device includes a sensor driving unit that drives a temperature sensor to be movable in an axial direction of a fixing rotating body, and a sensor position control unit that controls the position of the temperature sensor by the sensor driving unit. The sensor position control unit performs sensor position control for setting a sheet size identified by a size identification unit as a reference sheet size and allowing the temperature sensor to be located within a passage area of a sheet having the reference sheet size and a non-passage area of a sheet having a sheet size smaller by one size than the reference sheet size.

    IPC: G03G15/20

    Abstract: In a fixing device, a heater heats an endless rotatable fixing belt. A retention member includes a groove for retaining a lubricant and retains the heater such that a surface on a front side comes into contact with an inner circumferential surface of the fixing belt via the lubricant. A pressure member is pressed against the heater while the fixing belt is interposed therebetween and forms, with the fixing belt, a pressure region for heating and pressurizing a paper sheet onto which a toner image has been transferred. A guide guides the paper sheet to the pressure region. The guide causes the paper sheet to come into contact with the fixing belt at a position more on a downstream side of a rotation direction of the fixing belt than the groove, to guide the paper sheet to the pressure region.

    Abstract: A fixing device includes a fixing member, a pressure member, a separation member and a separation/contact mechanism. The fixing member and the pressure member are provided so as to separate away from or come in contact with each other and to form a fixing nip. The fixing member has a flexibility and is deformable by separating away from or coming in contact with the pressure member. The separation member is disposed to face the fixing member and configured to separate a sheet passed through the fixing nip from the fixing member. The separation/contact mechanism is configured to support the separation member such that a fixing member side edge portion of the separation member is deformed along the fixing member in synchronization with the separating and contacting of the fixing member and the pressure member.

    Abstract: A fixing device including: arms that support the heating roller and the pressure roller so as to be displaced between a pressure-contact attitude in which a nip portion is formed and a distanced attitude in which the nip portion is released; a solenoid that displaces the rollers to the distanced attitude; a separation plate that has an electric conductivity, is disposed to face the heating roller, and separates the sheet that has passed through the nip portion from the heating roller; and interlocking arms that, in interlock with displacement from the pressure-contact attitude to the distanced attitude by the solenoid, displace a first end portion of the separation plate to an attitude to be distanced away from the heating roller by a first distance, change the potential of the separation plate from a floating potential to a reference potential, and accelerate discharge between the heating roller and the separation plate.

    Abstract: A fixing device includes a heated roller member, a pressure member, a separation member, and a discharge state switching mechanism. The heated roller member is heated by heating means. The pressure member contacts with the heated roller member so as to form a fixing nip portion. The separation member is conductive and disposed with a predetermined gap to a surface of the heated roller member, so as to separate a recording medium after passing through the fixing nip portion from the heated roller member. The discharge state switching mechanism switches between a discharge permissive condition that permits discharge from the heated roller member to the separation member and a discharge restricted condition that restricts the discharge from the heated roller member to the separation member.
