Control apparatus and recording medium

A control apparatus for controlling an image forming system, wherein the image forming system includes transparent toner image forming device configured to form a transparent toner image on a sheet on which a color toner image has been fixed and includes fixing device configured to fix the transparent toner image formed on the sheet, said control apparatus comprising:

• color toner amount obtaining means for obtaining an amount per unit area of the color toner for the color toner image to be fixed on the sheet;
• obtaining means for obtaining information of a first part of a color toner image area on which transparent toner is to be applied with a first amount per unit area after the color toner image is fixed;
• and
• control means for controlling the transparent toner image forming device so that the transparent toner is selectively applied with a second amount on a second part, in which the amount per unit area of the color toner obtained by said color toner amount obtaining means is a predetermined amount or more per unit area, of the color toner image area which is the color toner image area excluding the first part, wherein the second amount is smaller than the first amount.

A control apparatus for controlling an image forming system, wherein the image forming system forms a transparent toner image on a sheet on which a color toner image has been fixed, said control apparatus comprising:

• image data obtaining means for obtaining image data used for forming the transparent toner image on a first part of a color toner image area on which transparent toner is to be applied with a first amount per unit area after the color toner image is fixed;
• image data generating means for generating image data so that the transparent toner is applied, with a second amount per unit area, on a second part of the color toner image area which is the color toner image area excluding the first part of the color toner image area on which the transparent toner image is to be formed on the basis of the image data obtained by said image data obtaining means, wherein the second amount is smaller than the first amount;
• and
• image data sending means for sending the image data generated by said image data generating means to the image forming system.

A recording medium, readable by a computer, storing a program capable of causing the computer to execute steps specified below so that image data used for forming a transparent toner image is sent to an image forming system for forming the transparent toner image on a sheet on which a color toner image has been fixed:

• an image data obtaining step of obtaining the image data used for forming the transparent toner image on a first part of a color toner image area on which transparent toner is to be applied with a first amount per unit area;
• an image data generating step of generating image data so that transparent toner is applied, with a second amount per unit area, on a second part of the color toner image area which is the color toner image area excluding the first part of the color toner image area on which the transparent toner image is to be formed on the basis of the image data obtained by said image data obtaining means, wherein the second amount is smaller than the first amount;
• and
• an image data sending step of sending the image data generated by the image data generating step to the image forming system.
