Abstract:
A curling device includes a first curling unit configured to curl a sheet in a first direction and a second curling unit. The second curling unit is for curling a sheet which has passed the first curling unit in a second direction which is opposite to the first direction. The curling device also includes an input unit facilitating manual inputting correction values relating to the curling direction and curling amount to be corrected, and a control unit configured to changeably control the curling amount of each of the first curling unit and the second curling unit, to correspond to the correction values input in the first and second input units.
Abstract:
In a construction wherein at the start of fixing, a pressure belt is brought into contact with a fixing roller at uniform timing, it has sometimes been the case that the temperature of the pressure belt at a point of time whereat the fixing is started does not become a desired temperature but faulty fixing occurs. The timing for bringing the pressure belt into contact with the fixing roller at the start of fixing is changed in accordance with the detected temperature of the pressure belt. By such a construction, faulty fixing can be prevented from occurring.
Abstract:
An image forming apparatus generates a PWM signal corresponding to input image data and controls a timing of a light source to emit a light beam based on the PWM signal in order to perform tone reproduction. The image forming apparatus includes a data processing unit configured to generate the PWM signal for one pixel based on image data for continuous two pixels in the image data. The data processing unit selects an origin of pulse growth in generation of the PWM signal for one pixel in accordance with the image data for the two pixels to generate the PWM signal.

Abstract:
An image forming apparatus of the present invention has an image forming device for forming an image on a recording material; a heating member heating the image formed on the recording material in a nip portion; an endless belt conveying the recording material toward the nip portion formed between itself and the heating member; and a contacting and separating device for bringing the heating member and the belt into contact with each other and for separating the heating member and the belt from each other, wherein when images are continuously formed on a plurality of recording materials, a separating operation can be executed by the contacting and separating device during a time period after the immediately preceding recording material passes through the nip portion and before the subsequent recording material arrives at the nip portion.

If the detected temperature of the belt reaches a predetermined temperature, an image formation job is interrupted, and the heating member and the belt are separated.
Abstract:
An image formation device changes the rotational rate of a polygon motor, i.e. the main-scanning rate, and selects one of pulse width conversion tables when an image formation is performed multiple times on a single sheet of transfer paper. The changing of the main-scanning rate is for preventing inconsistent sizes between a first recorded image and a second recorded image caused by shrinkage of transfer paper. The pulse width conversion tables allow the pulse widths to be modulated.
Abstract:
A control apparatus used in an image forming apparatus which is capable of improving development efficiency and decreasing development cost as well. A control apparatus comprises a CPU board 100 and a relay board having I/Fs 311-314 and a CPU 301. The I/Fs 311-314 are connectable with driver boards 5001-5004, and have common standards. The CPU 301 detects each connection state of the driver boards 5001-5004 to the I/Fs 311-314, decides an ID for the relay board 300 according to the connection state, and performs consistency control to secure consistency of control between the driver boards 5001-5004, based on the ID for the relay board 300. The CPU board 100 is communicatably connected to the relay board 300. The CPU board 100 obtains the ID for the relay board 300, and performs control according to the ID for the relay board 300.
