An electrostatic latent image is formed. This electrostatic latent image is developed with toner by the developing device 26c and transferred to the surface of the intermediate transfer belt 21 at a predetermined transfer position by the transfer device 26d. The residual charge on the photosensitive drum 26a is neutralized by the neutralization device 26e.

  Further, in the magenta color image forming unit 27, the surface of the photosensitive drum 27a is charged by the charger 27b, and the surface is exposed by the magenta image light 30b output from the optical writing unit 30, thereby corresponding to the cyan image. An electrostatic latent image is formed.

  Further, in the black image forming unit 29, the surface of the photosensitive drum 29a is charged by the charger 29b, and the surface is exposed by the black (monochrome) image light 30d output from the optical writing unit 30, so that the black ( An electrostatic latent image corresponding to the (black and white) image is formed. This electrostatic latent image is developed with toner by the developing device 29c, and transferred to the surface of the intermediate transfer belt 21 at a predetermined transfer position by the transfer device 29d. As a result, a cyan component toner image, a magenta component toner image, a yellow component toner image, and a black component toner image are transferred onto the surface of the intermediate transfer belt 21 at a predetermined transfer position. A full-color toner image is completed on the surface of the intermediate transfer belt 21 at a predetermined transfer position.

  On the other hand, the transfer paper 31 placed on any one of the paper feed trays (not shown) is picked up by the pair of paper feed rollers (not shown) and conveyed in the direction of the arrow RB. Then, in a state of being aligned with the full-color toner image on the surface of the intermediate transfer belt 21, the full-color image formed on the surface of the intermediate transfer belt 21 is sent to the transfer roller 32 that contacts the conveying roller 22. A toner image is transferred to the surface.

  FIG. 3 shows an example of processing when print data is transmitted from the host device and a printing operation is performed.

  First, it is checked whether or not the accumulation print mode is set at that time (decision 101). When the result of determination 101 is YES, print data for one page is input (process 102), and the input print data is sorted into print modes and stored in the buffer memory 7 (process 103).

  Here, for each print mode, for example, for each color mode (for each conveyance line speed), for each resolution (for each rotation speed of the polygon motor), or for each fixing target temperature (presence / absence of pre-rotation operation of the fixing unit). Or, indicates whether or not the option unit is used (option unit motor rotation).

  Then, it is checked whether or not the accumulation of the number of pages that can be accumulated in the buffer memory 7 is completed (determination 104). When the result of determination 104 is NO, the process returns to the process 102 and the next page is input.

  If the result of determination 104 is YES, a printing operation is executed (process 105).

  On the other hand, when the result of determination 101 is NO, the process proceeds to process 105 to execute a printing operation.

  In the above-described processing, it is determined whether or not the accumulation print mode is set, and the processing is switched according to the determination result. However, this determination may be omitted.

  In general, from the viewpoint of energy saving, it is efficient if as many sheets as possible can be printed per printing operation. In this embodiment, when a print request is made a plurality of times (n times) at 1 to 1, the output is performed in one print operation, thereby saving the total power required for printing and the life of the unit. In addition, by providing a plurality of printing conditions, fine control can be performed, so that a significant energy saving effect can be obtained.

  Further, since the reference value is set to the color mode, fine control can be performed, and the life of each color unit can be saved, so that a significant energy saving effect can be obtained.

In addition, since the above-mentioned condition is the image resolution, fine control can be performed, and the life of the polygon motor and laser unit used for writing control can be saved, so that a significant energy saving effect can be obtained.
In addition, by setting the above conditions for each fixing target temperature set for each paper type, continuous heater control can be performed, so that waste of power used by the fixing unit can be suppressed, and a significant energy saving effect is obtained. be able to.

  Moreover, since continuous conveyance control can be performed for each option unit using the above conditions, the power and life used by the option unit can be suppressed, and a significant energy saving effect can be obtained.

  Next, another embodiment of the present invention will be described. Since the present embodiment has the same configuration as the above-described embodiment, description of the configuration is omitted. In this embodiment, the print interval time, the print designation time, and the standard mode information as shown in FIG. 4A are designated by the user or the like, and are stored in the system memory 2 or the parameter memory 3, for example. .

  The standard mode information has values of a default color mode, a default resolution, a default fixing temperature, and a default option unit, as shown in FIG.

  FIG. 5 shows an example of processing when print data is transmitted from the host device and a printing operation is performed in this case.

  First, it is checked whether or not the accumulation print mode is set at that time (decision 201). When the result of determination 201 is YES, print data for one page is input (process 202), and the input print data is sorted by print mode and stored in the buffer memory 7 (process 203).

  Here, for each print mode, for example, for each color mode (for each conveyance line speed), for each resolution (for each rotation speed of the polygon motor), or for each fixing target temperature (whether the pre-rotation operation of the fixing unit is performed) Or, indicates whether or not the option unit is used (option unit motor rotation).

  Then, it is checked whether or not the accumulation of the number of pages that can be accumulated in the buffer memory 7 is completed (determination 204). When the result of determination 204 is NO, the process returns to the process 202 and the next page is input.

  When the result of determination 204 is YES, the process waits until the time specified by the print interval time elapses from the previous printing operation (NO loop of determination 205), and then executes the printing operation (process 206). .

  On the other hand, when the result of determination 201 is NO, the process proceeds to process 205 to execute a printing operation.

  FIG. 6 shows another example of processing in this case when print data is transmitted from the host device and a printing operation is performed.

  First, it is checked whether or not the accumulation print mode is set at that time (determination 301). When the result of determination 301 is YES, print data for one page is input (process 302), and the input print data is sorted by print mode and stored in the buffer memory 7 (process 303).

  Here, for each print mode, for example, for each color mode (for each conveyance line speed), for each resolution (for each rotation speed of the polygon motor), or for each fixing target temperature (whether the pre-rotation operation of the fixing unit is performed) Or, indicates whether or not the option unit is used (option unit motor rotation).

  Then, it is checked whether or not the accumulation of the number of pages that can be accumulated in the buffer memory 7 has been completed (determination 304).

  If the result of determination 304 is YES, the process waits until the print designation time has elapsed (NO loop of determination 305), and then executes a printing operation (process 306).

  On the other hand, when the result of determination 301 is NO, the process proceeds to process 305 to execute a printing operation.

  FIG. 7 shows another example of processing when print data is transmitted from the host device and a printing operation is performed in this case. In this case, the mode used when sorting the print pages is the color mode.

  First, it is checked whether or not the accumulation print mode is set at that time (decision 401). When the result of determination 401 is YES, print data for one page is input (process 402), and whether or not the color mode of the input print data is different from the set default color mode. Check (decision 403). If the result of determination 403 is NO, that is, in the case of the default color mode, the input print data is sorted by print mode and stored in the buffer memory 7 (process 404).

  Then, it is checked whether or not the accumulation of the number of pages that can be accumulated in the buffer memory 7 is completed (determination 405). When the result of determination 405 is NO, the process returns to the process 402 and the next page is input.

  If the result of determination 405 is YES, the process waits until the print designation time elapses (NO loop of determination 406), and then executes a printing operation (process 407).

  On the other hand, when the result of determination 403 is YES and when the result of determination 401 is NO, the process proceeds to process 407 to execute the printing operation.

  In this case, the process waits until the designated time elapses in the determination 406, but may wait until a predetermined time elapses from the previous printing operation.

  In this way, in this case, when print data of a color mode other than the default color mode is exceptionally input, printing is performed immediately, so that the work efficiency can be improved.

  FIG. 8 shows still another example of processing when print data is transmitted from the host device and a printing operation is performed in this case. In this case, the mode employed when sorting the print pages is the resolution mode.

  First, it is checked whether or not the accumulation print mode is set at that time (decision 501). When the result of determination 501 is YES, print data for one page is input (process 502), and whether or not the resolution mode of the input print data is different from the set default resolution mode. Check (judgment 503). If the result of determination 503 is NO, that is, in the case of the default resolution mode, the input print data is sorted by print mode and stored in the buffer memory 7 (process 504).

  Then, it is checked whether or not the accumulation of the number of pages that can be accumulated in the buffer memory 7 is completed (determination 505). When the result of determination 505 is NO, the process returns to the process 502 and the next page is input.

  If the result of determination 505 is YES, the process waits until the print designation time elapses (NO loop of determination 506), and then executes a printing operation (process 507).

  On the other hand, when the result of determination 503 is YES and when the result of determination 501 is NO, the process proceeds to step 507 to execute a printing operation.

  In this case, the process waits until the specified time elapses in the determination 506, but may wait until a predetermined time elapses from the previous printing operation.

  Thus, in this case, when print data in a resolution mode other than the default resolution mode is exceptionally input, the printing is performed immediately, so that the work efficiency can be improved.

  FIG. 9 shows still another example of processing when print data is transmitted from the host device and a printing operation is performed in this case. In this case, the mode adopted when sorting the print pages is the fixing temperature mode.

  First, it is checked whether or not the accumulation print mode is set at that time (decision 601). When the result of determination 601 is YES, print data for one page is input (process 602), and the fixing temperature (fixing target temperature) mode of the input print data is different from the set default fixing temperature mode. It is checked whether or not it is a thing (decision 603). If the result of determination 603 is NO, that is, in the case of the default fixing temperature mode, the input print data is sorted according to the print mode and stored in the buffer memory 7 (process 604).

  Then, it is checked whether or not the accumulation of the number of pages that can be accumulated in the buffer memory 7 is completed (determination 605). When the result of determination 605 is NO, the process returns to process 602 and the next page is input.

  If the result of determination 605 is YES, the process waits until the print designation time elapses (NO loop of determination 606), and then executes a printing operation (process 607).

  On the other hand, when the result of determination 603 is YES and when the result of determination 601 is NO, the process proceeds to step 607 to execute a printing operation.

  In this case, the process waits until the specified time elapses in the determination 606, but may wait until a predetermined time elapses from the previous printing operation.

  In this way, in this case, when print data in a fixing temperature mode other than the default fixing temperature mode is exceptionally inputted, printing is performed immediately, so that the work efficiency can be improved.

  FIG. 10 shows still another example of processing when print data is transmitted from the host device and a printing operation is performed in this case. In this case, the mode adopted when sorting the print pages is the option unit mode.

  First, it is checked whether or not the accumulation print mode is set at that time (decision 701). When the result of determination 701 is YES, print data for one page is input (process 702), and the option unit mode (option unit to be used) of the input print data is the set default option unit mode. It is checked whether they are different (decision 703). When the result of determination 703 is NO, that is, in the case of the default option unit mode, the input print data is sorted according to the print mode and stored in the buffer memory 7 (process 704).

  Then, it is checked whether or not the accumulation of the number of pages that can be accumulated in the buffer memory 7 is completed (determination 705), and when the result of the determination 705 is NO, the process returns to the process 702 and the next page is input.

  If the result of determination 705 is YES, the process waits until the print designation time elapses (NO loop of determination 706), and then executes a printing operation (process 707).

  On the other hand, when the result of determination 703 is YES and when the result of determination 701 is NO, the process proceeds to process 707 to execute a printing operation.

  In this case, the process waits until the designated time elapses in the determination 706, but may wait until a predetermined time elapses from the previous printing operation.

  As described above, in this case, when print data in an option unit mode other than the default option unit mode is exceptionally input, printing is performed immediately, so that the work efficiency can be improved.

  In the above-described embodiment, the case where the present invention is applied to the network-compatible image forming apparatus has been described. However, the present invention can be applied to other image forming apparatuses in the same manner.
