Next, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows an entire image forming apparatus 10 according to an embodiment of the present invention. The image forming 10 includes a control device 12 and an image forming apparatus main body 14. The control device 12 and the image forming apparatus main body 14 are connected by, for example, a wired connection.

  The control device 12 is, for example, a server, and upon receiving a job, converts the job data into raster data and sends it to the image forming apparatus main body 14. Moreover, the control apparatus 12 has the display operation part 16 which consists of touch panels, for example. The image forming apparatus main body 12 is controlled by operation setting data input from the display operation unit 16.

FIG. 2 shows a main part of the image forming apparatus main body 12.
The image forming apparatus main body 12 includes a transfer target member 18 that is an intermediate transfer belt. This transferred member 18 is supported by a plurality of support rolls 20 and rotates in the direction of the arrow (clockwise) in the figure. Below the transferred member 18, for example, six developer image forming portions 22G, 22Y, 22M, 22C, 22K, and 22S are arranged in series.

  The six developer image forming units 22G, 22Y, 22M, 22C, 22K, and 22S are, from the upstream side, the center four, yellow developer image forming unit 22Y, magenta developer forming unit 22M, and cyan developer forming unit. 22C, for a basic color composed of a black developer forming portion 22K. On both sides of the basic color developer image forming portions 22Y, 22M, 22C and 22K, special color developer image forming portions 22G and 22S are provided. For example, the upstream developer image forming portion 22G is gold, and the downstream developer image forming portion 22S is silver.

  Each of the developer image forming portions 22G, 22Y, 22M, 22C, 22K, and 22S has the same structure. As shown in FIG. 2, the developer image forming portion 22C is numbered as a representative. 24. Around the photoconductor 24, a developing device 26, a charger 28 and a photoconductor cleaning device 30 are arranged in a clockwise direction. When the photosensitive member 24 is charged by the charger 28, a latent image is formed on the photosensitive member 24 by light from an exposure unit (not shown), and the formed latent image is developed by the developing unit 26.

  The primary transfer roll (transfer portion) 28 faces the photosensitive member 24 of the developer image forming portion 22 with the transfer target member 18 interposed therebetween. When the primary transfer roll 28 is in contact with the member 18 to be transferred, the developer on the photosensitive member 24 is attracted by the potential, and the developer image developed by the developing device 26 is transferred to the member 18 to be transferred. When the transfer from the transfer member 18 is completed, the developer on the photoconductor 24 is cleaned by the photoconductor cleaning device 30.

  The primary transfer roll 28 has a mechanism that moves between a position away from the transferred member 18 (retract position) and a position in contact with the transferred member 18 (contact position). At the retract position, the pressing from the position transfer roll 28 is eliminated, so that the member to be transferred 18 is separated from the photoconductor 24. Further, the rotation of the photosensitive member 24, the developing device 26, and the charging device 28 is stopped. In the example of FIG. 2, the gold developer image forming portion 22G and the silver developer image forming portion 22S are in the retracted position. When in the retract position, the developer forming portion is stopped, so that consumption of consumables is suppressed.

  The secondary transfer roll 32 is provided to face the support roll 20 provided at one end in the longitudinal direction of the transfer member 18. The recording medium is conveyed between the transfer member 18 and the secondary transfer roll 34. The secondary transfer roll 34 transfers the developer image conveyed by the transfer target member 18 to a recording medium. In FIG. 2, the recording medium is conveyed from below to above.

  The transferred member cleaning device 34 is provided to face the support roll 20 provided at the other longitudinal end of the transferred member 18. The transfer member cleaning device 34 cleans the developer remaining on the transfer member 18 on the downstream side of the secondary transfer roll 32.

FIG. 3 is a block diagram showing the hardware of the control device 12.
The control device 12 includes a CPU 36, a memory 38, and an input / output interface 40.

  The CPU 36 executes a predetermined process based on a control program stored in the memory 38.

  The input / output interface 40 is connected to the image forming apparatus main body 14 and the display operation section 16, and the image forming apparatus main body is brought into a control state (control mode) set by the display operation section 16 via the input / output interface 40. 14 is controlled.

  The CPU 36, the memory 38 and the input / output interface 40 are connected via a control bus 42.

Next, the software configuration of the control device 12 will be described.
FIG. 4 shows a conceptual software configuration of the control device 12.
In FIG. 4, “unit” refers to a component that constitutes software, but may be constituted by hardware.

  The print control unit 44 acquires the number of usable developer image forming units and the color of the developer from the image forming apparatus main body 14.

  The job management unit 46 notifies the print control unit 44 of a print instruction based on the input job data.

  The selection receiving unit 48 notifies the print control unit 44 of the control mode selected by the user. The print control unit 44 instructs the image forming apparatus main body 14 to print the job received from the job management unit 46 in the control state received by the selection receiving unit 48.

FIG. 5 shows an example of the selection screen displayed on the display operation unit 16 described above.
When the “Server” tab is clicked, an area “prioritizing productivity when mixing color and black and white” is displayed. Here, when the button 50 is clicked, a selection branch for selecting “off”, “on (standard)”, and “on (speed priority)” is displayed.

  FIG. 6 shows a control flow when the user selects a control state.

  First, in step S10, the control state selected by the user is received. Either “off”, “on (standard)”, or “on (speed priority)” is accepted.

  In step S12, the control state accepted in step S10 is determined. In this step S12, when it is determined as “ON (standard)”, the process proceeds to step S14 to set the first control state. The first control state is a mode determined for each job. That is, for each job sent, the developer color used for each page of the job is determined before the start of the job, and the transfer portion corresponding to the developer color that is not used is separated from the transferred member and used. The transfer portion corresponding to the developer color is brought into contact with the member to be transferred, and is fixed in this state until one job is completed. A balance between productivity and consumable consumption control is maintained.

  In step S12, when it is determined that “off” is set, the process proceeds to step S16 to set the second control state. The second control state is a mode for controlling which transfer unit is to be separated from the transfer target member for each recording medium to be continuously printed.

FIG. 7 shows an example of the second control state.
Note that a portion with a + symbol is a portion where there is an operation of bringing the transfer portion into contact with the member to be transferred.

  When the first recording medium 1 of job 1 is monochrome, only the developer image forming unit 22K is used. When the next recording medium 2 is color, the transfer unit corresponding to the developer image forming units 22Y, 22M, and 22Y contacts the transfer target member, and the developer image forming units 22Y, 22M, 22Y, and 22K are used. . When gold is used for the next recording medium 3, a developer image forming unit 22G is added. When job 1 is finished and job 2 is started, it is reset once. When the first recording medium 1 of job 2 is monochrome, only developer image forming unit 22K is used. When the next recording medium 2 is a color, a transfer portion corresponding to the developer image forming portions 22Y, 22M, and 22Y is added in contact with the transferred member, and the developer image forming portions 22Y, 22M, 22Y, and 22K are added. Used. When gold is used for the next recording medium 3, a developer image forming unit 22G is added, and when silver is used for the next recording medium 4, a developer image forming unit 22S is added. When job 2 is finished and job 3 is started, it is reset once. When the first recording medium 1 of job 2 is color, the transfer unit corresponding to developer image forming units 22Y, 22M, 22Y, 22K. Contacts the transfer member, and the developer image forming portions 22Y, 22M, 22Y, and 22K are used. When the next recording medium 2 is a color, the contact operation is not necessary. When gold is used for the next recording medium 3, a developer image forming unit 22G is added.

  As described above, in the second control state, it is determined which transfer unit is to be brought into contact with the member to be transferred for each recording medium (which transfer unit is not to be brought into contact with the transfer unit), so that consumption of consumables is suppressed. On the other hand, productivity will drop.

  In the above embodiment, the transfer portion to be contacted is determined by the logical sum of the developer color used for the previous recording medium and the developer color used for the next recording medium. However, the present invention is not limited to this. It is not a thing. For example, when the previous recording medium is color and the next recording medium is black and white, the developer images 22Y, 22M, and 22C may be retracted. In addition, the contact and retract operations may be performed only when a special color (here, gold or silver) is used.

  Returning to FIG. 6, if it is determined in step S12 that “ON (speed priority)” is set, the process proceeds to step S18 to set the third control state. The third control state is a mode for controlling whether or not the transfer unit is separated from the transfer target member over a plurality of jobs to be printed continuously.

FIG. 8 shows an example of the third control state.
As in FIG. 6, a portion with a + sign is a portion where there is an operation of bringing the transfer unit into contact with the member to be transferred.

  As shown in FIG. 8A, in the case of a single job (one accepted job), the transfer unit corresponding to the developer color used in the job is set as the transfer target unit as in the first control state. Make contact.

  As shown in FIG. 8B, in the case of a multi-job (a plurality of received jobs), the developer image forming unit to be used is determined by calculating the logical sum of the developer colors used for each job. . Here, when gold and silver are used for either job 1 or job 2, before starting job 1, transfer units corresponding to the developer image forming units 22Y, 22M, 22C, 22K, 22G, and 22S are provided. The member to be transferred is brought into contact, and the job 2 is fixed as it is.

  In this way, in the third control state, since it is determined which transfer part is to be separated from the transferred part over a plurality of jobs (which transfer part is not brought into contact with the transferred part), “off (standard)” is determined. Compared with, productivity is good, but consumption of consumables becomes large.

  In the above embodiment, the logical sum of the developer colors used for each job is calculated, but the present invention is not limited to this. For example, even when silver is not included, the transfer portion corresponding to silver may be brought into contact with the transferred portion.

  When the control state is set in steps S14, S16, and S18, the process proceeds to the next step S20 to instruct the image forming apparatus body to control the image forming apparatus body in the set control state.

  FIG. 9 shows a control flow in the second control state (productivity off).

  First, in step S22, the usage state of the developer image forming unit used for the recording medium to be printed first is acquired. Let this use state be C. The initial value of C is 0 (blank paper).

  In the next step S24, the usage state of both sides of the recording medium is acquired, and the logical sum X of the front and back C is acquired.

  In the next step S26, it is determined whether or not X is a blank sheet. X being a blank sheet means that there is no recording medium to be printed first, and the recording medium is a blank sheet.

  If it is determined in step S26 that X is a blank sheet, the process advances to step S28 to use the developer image forming unit specified in the job. On the other hand, if X is not white paper, that is, there is a recording medium to be printed first and the recording medium to be printed first is not white, or the recording medium is not white, the process proceeds to step S30. In step S30, the developer image forming unit set by X is used.

  When the process of step S28 or S30 is completed, the process proceeds to step S32, X is set in C, and the process is terminated.

  FIG. 10 shows a control flow in the third control state (productivity on (speed priority)).

  First, in step S34, it is determined whether the job is a multi-job. If it is determined in step S34 that the job is not a multi-job, that is, a single job, the process proceeds to step S36, and the developer image forming unit used in the job is used.

  On the other hand, if it is determined in step S34 that the job is a multi-job, the process proceeds to step S38, and the usage state D of the developer image forming unit to be printed first is acquired. The initial value of D is NULL.

  In the next step S40, the developer image forming unit according to the logical sum of the use state D to be printed in the previous job and the use state to be printed in the job is used.

  When the process of step S36 or S40 ends, the process proceeds to the next step S42, the use state of the developer forming part of the job is set to D, and the process ends.

  In the above embodiment, the developer colors of the image forming apparatus are 6 colors in total using gold and silver as special colors. However, the present invention is not limited to this, and transparent and white are added. be able to. Further, although a server separate from the image forming apparatus main body is used as the control apparatus, the present invention is not limited to this, and the image forming apparatus main body and the control apparatus may be integrated.
