摘要： A charging brush unit includes a brush and a conductive holder. The brush includes a plurality of flexible conductive fibers. The plurality of flexible conductive fibers is supplied with a charging bias to generate electrical discharge between a top of the plurality of conductive fibers and a latent image carrier across a gap formed between the top of the plurality of conductive fibers and the latent image carrier. The gap is provided with an electrode. The electrode includes a plurality of openings opposing the top of the plurality of conductive fibers and is supplied with a bias different from the charging bias applied to the plurality of conductive fibers. The conductive holder holds the brush.

摘要： A fixing device includes a fixing member, a pressing member, a temperature detector, and a heater. The pressing member contacts an outer circumferential surface of the fixing member to form a fixing nip between the fixing member and the pressing member through which a recording medium bearing a toner image passes. The heater heats the fixing member to a predetermined temperature based on a detection result provided by the temperature detector. A circumferential distance A between the temperature detector and the heater along a circumference of the fixing member is defined by the following formula: A≧v×(T1+T2) where v is a circumferential velocity of the fixing member rotating in a predetermined direction of rotation, T1 is a response time of the temperature detector, and T2 is a response time of the heater.

摘要： A fixing device for fixing an unfixed toner image on a recording medium includes a rotatable fixing member heated by a heater to contact the recording medium bearing the unfixed toner image while rotating, with the heater disposed inside a hollow of the fixing member and turned on and off intermittently at a start of a fixing process to heat the fixing member intermittently, a first pressing member disposed opposite the fixing member to press against and rotate the fixing member to define a fixing nip through which the recording medium passes to fix the unfixed toner image with heat and pressure, and a temperature detector to detect a change in the temperature of the fixing member when the heater turns on and off intermittently. When the temperature detector detects the change in the temperature of the fixing device, the heater is turned on continuously.

摘要： In a fixing device, a first reflection plate covers a part of an outer circumferential surface of an infrared heater in a circumferential direction of the infrared heater along an axial direction of the infrared heater substantially perpendicular to the circumferential direction of the infrared heater. The first reflection plate reflects light emitted by the infrared heater toward a fixing member. At least one light control mirror is provided in at least one end of the first reflection plate in an axial direction of the first reflection plate. At least one second reflection plate opposes the infrared heater via the at least one light control mirror to reflect the light emitted by the infrared heater and passing through the at least one light control mirror toward a center portion of the fixing member in an axial direction of the fixing member.
