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.

In an image forming apparatus having a discrimination mechanism that identifies an input document image as a color image or a monochrome image and an area recognition mechanism that recognizes a plurality of different areas contained in the document image, the apparatus applies the optimum color image forming mode even if the document is identified as a color image and forms an image. The user is permitted to select either a first color image forming mode that uses recording agents of m colors (where m is a natural number equal to or greater than 4) or a second color image forming mode that uses recording agents of n colors (where n is a natural number equal to or greater than m+1) as a color image forming mode applied to at least one of the areas recognized by the area recognition mechanism. If the input document image is identified as a color image, the apparatus applies the selected color image forming mode to at least one of the areas recognized by the area recognition mechanism and forms an image.

An image forming apparatus that can provide a quality image in a stable manner without lowering the productivity. A reference image forming unit forms reference images on a transfer member. A plurality of sensing units detect densities of the formed reference images. A control unit adjusts respective output values from the plurality of sensing units according to a difference between the output values from the plurality of sensing units. The control unit performs error processing according to the difference between the output values from the plurality of sensing units when the control unit adjusts the output values from the plurality of sensing units.
摘要:
An image forming apparatus is operable in a speed priority mode in which a temperature range that permits a fixing operation via a pressure belt is wide and an image-quality priority mode in which a temperature range that permits a fixing operation via the pressure belt is narrow. A user interface of the image forming apparatus is configured to enable an operator to select the speed priority mode or the image-quality priority mode for a coated paper.

A image forming system that can prevent a toner from coming off while reducing the amount of consumption of a clear toner in binding sheets into a book. An image forming apparatus 100 forms an image on a sheet. A clear coating apparatus 200 forms a clear coating image on the sheet using the clear toner that becomes transparent after fixing. A bookbinding apparatus 600 connected to the image forming apparatus 100 and the clear coating apparatus 200 subjects the sheet to folding process. A job controller 501 and an image controller 502 cause the clear coating apparatus 200 to form the clear toner image at a folding position on the sheet in response to designation of a folding mode in the bookbinding apparatus 600.

An image processing apparatus comprising an image processing unit configured to execute image processing by selectively using a plurality of image processing patterns, a selecting unit configured to select one of the plurality of image processing patterns according to a user's operation, a determination unit configured to determine whether or not tone correction control has been applied to the image processing pattern selected by the selecting unit, and a notification unit configured to notify, when the determination unit determines that the tone correction control has not been applied yet, a message that advises accordingly.
摘要:
In an image forming apparatus including a fixing device that uses a pressure belt as at least one of two pressing members, a warm-up time and time for shifting to a standby state are reduced with simple control without increasing power consumption. The two pressing members are brought into a press-contact state by a contacting/separating mechanism and only heating means on the upper side is turned on. When the temperature of the upper pressing member increases to temperature near a target temperature corresponding thereto, the pressing members are driven to rotate. When it is detected by temperature detecting means on the lower side that the temperature of the lower pressing member increases to temperature near a target temperature corresponding thereto, the two pressing members are brought into a separated state by the contacting/separating mechanism.
