摘要： Heat-equalizing rotation of a fixing member and a pressing member for equalizing the distribution of the temperature of a surface of the fixing member in a width direction is performed after a recording medium having a size less than or equal to a predetermined size in the width direction passes a nip portion and before a recording medium having a size greater than the predetermined size in the width direction passes the nip portion. Further, a termination condition of the heat-equalizing rotation is selected from among a plurality of different kinds of termination conditions, based on image formation related information related to next image formation performed after the heat-equalizing rotation.

摘要： When calculating an actual turn-on duty based on a required duty according to a feedback control, the actual turn-on duty is corrected using a correction table or a correction conversion formula such that a required turn-on duty and the actual turn-on duty coincide with each other. A fixing heater is controlled according to the corrected actual turn-on duty.

摘要： A fixing device includes a heat source; a fixing member looped into a generally cylindrical shape to rotate in a circumferential direction thereof and partially heated by the heat source and to heat a surface of a recording medium bearing an unfixed toner image to fix the unfixed toner image thereon in a fixing process; a rotary pressing member disposed facing the fixing member to form a nip therebetween, through which the recording medium is transported in a transport direction; and a rotation driver to rotate one of the fixing member and the pressing member. In a case in which the fixing member is halted for a reason other than the fixing process while power of the fixing device is on, electric power is not supplied to the heat source and the fixing member is rotated by a predetermined amount or more after the fixing member is halted.

摘要： A fixing device includes a controller connected to a heater and at least one of a pressing rotary body and an endless rotary body. The controller performs a first fixing operation, a first transition operation, a second fixing operation, and a second transition operation. The first fixing operation fixes a toner image on a first recording medium after the fixing device is powered on. The first transition operation rotates the pressing rotary body and the endless rotary body while controlling the heater to maintain the endless rotary body at a predetermined temperature for a first duration time. The second fixing operation fixes a toner image on a second recording medium. The second transition operation rotates the pressing rotary body and the endless rotary body while controlling the heater to maintain the endless rotary body at the predetermined temperature for a second duration time smaller than the first duration time.

摘要： An optical sensor includes a light-emitting unit to emit light onto a measuring object, a regular reflection light receiver to receive regular reflection light from the measuring object out of the light emitted by the light-emitting unit, and a diffuse reflection light receiver to receive diffuse reflection light from the measuring object out of the light emitted by the light-emitting unit. An angle of incidence of the light emitted onto a surface of the measuring object is not smaller than 75° and not larger than 85°. The diffuse reflection light receiver receives, out of the diffuse reflection light from the measuring object, diffuse reflection light having an angle of reflection with respect to a perpendicular to the surface of the measuring object larger than 0° and smaller than an angle of reflection of the regular reflection light with respect to the perpendicular to the surface of the measuring object.

摘要： An image forming apparatus includes an image forming part, a fixer including a heating member and a pressure member, a reverse transport part to forward a recording medium transported from the fixer to the image forming part, a toner image sensor to detect presence of a toner image on the recording medium, and a controller. When a glossy image formation mode is selected and no toner image is detected on the recording medium, the image forming part does not form a toner image on the recording medium, the fixer performs a first heating and pressing process and transports the recording medium to the reverse transport part, the reverse transport part transports the recording medium to the image forming part, the image forming part forms a toner image on the recording medium transported from the reverse transport part, and the fixer performs a second heating and pressing process and fixes the toner image thereon.
