摘要： According to one embodiment, a temperature control device stores a fixing device temperature estimation value and a storage time obtained by WAE control in a memory at any time during operation. After an electric power supply to the temperature control device is stopped, the next time the electric power supply is started, an electric power supply stop period until the electric power supply is started is calculated. If the electric power supply stop period is shorter than a set time, the WAE control is started by using the stored fixing device temperature estimation value, and if the electric power supply stop period exceeds the set time, the WAE control is started based on an initial set value.

摘要： An image forming apparatus includes an image forming unit, a fixing unit, a sheet discharge unit to stack sheets, an acquisition unit, and a controller. The fixing unit fixes a toner image formed on a sheet by the image forming unit. The acquisition unit acquires information corresponding to a maximum toner application amount per unit area of the formed toner image. The controller controls the number of image formations on the sheets per unit time based on the acquired information. The controller executes a first job with a first number of image formations on the sheets per unit time during a period from an Lth sheet to an Mth sheet in the first job, and executes a second job with a second and smaller number of image formations on the sheets per unit time during the period from the Lth to the Mth sheet in the second job.

摘要： A hot fuse printer system includes a feeder module adapted to spool a continuous substrate and cut the substrate to a desired length; a sheeting module adapted to feed the cut substrate to a printer module, which includes a hot fuser unit adapted to print on the cut substrate. The feeder module may include at least one sensor configured to determine a length of the substrate. The feeder module, the sheeting module and the printer module are each operatively connected to a controller which is configured to cause the feeder module to cut the substrate in a desired location, the sheeting module to feed the cut substrate to the printer module, and the printer module to print onto the cut substrate in a desired manner.

摘要： In accordance with an embodiment, an image processing apparatus comprises a human sensor, a fixing device and a controller. The human sensor detects a person in the vicinity of the image processing apparatus. The fixing device carries out fixation of an image formed with a decolorable recording agent serving as a recording agent containing a coloring agent which is decolored through heating on a medium and decoloration of the image formed on the medium. The controller controls the fixing device to stop the decoloration of the image when the person is detected by the human sensor.

摘要： The invention relates to molding of a roller in which a roller body is provided integrally on the outer periphery of an axial core member, and the objective of the invention is to prevent the generation of a thin burr, and damage to the die. In order to achieve this objective, a die is provided with a first split die and a second split die which can butt against one another or separate from one another at mutually-opposing parting surfaces. A roller body molding surface, a cavity being defined between the axial core member and the roller body molding surface when the mold is clamped; and recessed portions which are located at both end portions of the supporting portions and extend along the parting surfaces, and which are not in contact with the outer peripheral surface of the axial core member when the mold is clamped.
