Method and apparatus for forming an image on an image transfer medium and a method of forming an image using the image transfer medium

An image forming apparatus for forming an image on an image transfer medium, comprising:

• inputting means for inputting image data;
• image processing means for generating one color primer image data at least on an area of the input image data from said inputting means;
• image forming means for forming an image on the image transfer medium according to the input image data from said inputting means and forming a primer image on top of the image according to the image data on the image transfer medium according to the one color primer image data from said image processing means, and transferring the primer image and image according to the image data to a recording medium such that the primer contacts the recording medium.

An image forming apparatus for forming an image on an image transfer medium, comprising:

• inputting means for inputting image data;
• image processing means for generating one color primer image data at least of a first area of the input image data from said inputting means;
• image forming means for forming an image according to the input image data from said inputting means and forming a primer image according to the one color primer image data from said image processing means on top of the image according to the image data on the image transfer medium by one color primer toner which includes at least a sintering coloring material and a binder resin, and transferring the primer image and image according to the image data to a recording medium such that the one color primer toner contacts the recording medium.

An image forming apparatus for forming an image on an image transfer medium, comprising:

• an image inputting unit for inputting image data;
• an image processing unit for generating one color primer image data at least on an area of the input image data from said image inputting unit;

A method of forming an image on an image transfer medium, comprising the steps of:

• forming an image according to image data on the image transfer medium;
• forming one color primer image by one color primer on the image transfer medium at least in a first area of said image and a second area which is larger than the first area according to the image data;
• wherein in said second area a density of said one color primer changes with an increasing distance from said first area.

A method of forming an image on an image transfer medium, comprising the steps of:

• forming a toner image, by toner which includes at least a first sintering coloring material and a first binder resin, according to image data on the image transfer medium;
• forming one color primer image, by one color primer toner which includes at least a second sintering coloring material and a second binder resin, on the image transfer medium at least in a first area of said image and a second area which is larger than the first area according to the image data;
• wherein in said second area a density of said one color primer toner changes with an increasing distance from said first area.
