摘要： An image forming apparatus includes an image forming device that forms an image on a recording medium and circuitry that controls the image forming device. The image forming device forms an invisible image with an invisible material on the recording medium and forms a visible image with a visible material on the invisible image. Each of first and second adhesion amounts includes respective adhesion amounts of the visible material and the invisible material per unit area in a portion, in which the visible image is formed on the invisible image, of the composite image. The second adhesion amount is smaller than the first adhesion amount. The controller adjusts the amount of the invisible material included in the second adhesion amount to be smaller than that included in the first adhesion amount, to cause the image forming device to form the image according to the second adhesion amount.

摘要： A solenoid device has a solenoid and a control portion. The solenoid has a body, a plunger, an attracting coil, a retaining coil, and a biasing member. The plunger is arranged selectively either in an attracted position, pulled into the body, or in a returning position, protruding out of the body. Fed with a voltage, the attracting coil generates an attracting force causing the plunger to move from returning position to attracted position. Fed with a voltage, the retaining coil generates a retaining force, weaker than the attracting force, causing the plunger to move to attracted position. The biasing member biases the plunger toward returning position. The control portion controls operation of the solenoid. When moving the plunger from returning position to attracted position, the control portion first starts applying the voltage to the retaining coil and then starts applying the voltage to the attracting coil.

摘要： An image forming apparatus includes a sheet feed unit which feeds a sheet to an image forming unit forming an image on the sheet, a re-transport roller which reverses the sheet with a toner image fixed on the sheet and re-transports the sheet to the image forming unit, and a control unit which controls a sheet feed operation of the sheet feed unit for feeding the sheet. As the temperature of the re-transport roller sensed by the temperature sensing unit is decreased, the control unit retards the timing at which the sheet feed unit starts the sheet feed operation when a duplex image formation in which the image is formed on both sides of the sheet is performed after a one-side image formation is completed.

摘要： An image forming apparatus has a pair of registration rollers which are moved in the width direction so that a sheet side end position is within a predetermined range in the width direction based on sheet side end position information from a lateral registration detection sensor. In the case that an image-formed sheet is conveyed to a sheet processing portion without being reversed, the pair of registration rollers are moved so that the sheet side end position is within the first range, and in the case that an image-formed sheet is conveyed to the sheet processing portion, the pair of registration rollers are moved so that the sheet side end position is within the second range being different from the first range before reversing and within the first range after reversing.

摘要： An image forming apparatus includes an apparatus body, an image forming unit, and a retransporting unit. The retransporting unit includes a transporting roller for applying a transporting force to the sheet and an input portion disposed at a position shifted upstream of the transporting roller in a retransporting direction. The input portion is configured to receive an input of a drive force supplied from the apparatus body. The retransporting unit further includes a drive shaft extending in a retransporting direction. The drive shaft is configured to transmit the drive force from the input portion toward the transporting roller by rotating about an axis thereof. A height of the image forming apparatus may be reduced by this configuration.

摘要： When an image is formed on a second side of a sheet, the image forming position is adjusted on the basis of a value calculated using the amount αn of lateral registration deviation detected before forming an image on the first side and the amount γn-1, of lateral registration deviation of the previous sheet on which image formation is performed. Thus, it is possible to adjust the positions of irradiation of laser light to the photosensitive drums and to start forming the second-side images as soon as the first-side images have been primary-transferred onto the intermediate transfer belt.
