Abstract
An image forming device 1 comprises an electrophotographic processing unit 48 equipped with a developer 44 including a developing agent containing black toner having infrared reflectiveness, and forms an image having infrared reflective property. The image forming device 1 further comprises a detector 51 for detecting whether the formed toner image has infrared reflective property or not and a control unit for controlling each unit based on the result of detection by the detector 51, so as to form a black image having infrared reflective property in a reliable manner.
Claims11
An image forming device for forming an image by transferring and fixing a toner image on a recording medium, comprising:
- a reader for reading a document image, an electrostatic latent image forming unit for converting the obtained image data into an electrostatic latent image, an electrophotographic processing unit for forming a toner image to the electrostatic latent image portion, and a control unit for controlling operation of each unit;
- wherein said electrophotographic processing unit comprises a developing agent containing an azomethine black organic pigment, and the formed image has infrared reflective property.
An image forming device for forming an image by transferring and fixing a toner image on a recording medium, comprising:
- a reader for reading a document image, an electrostatic latent image forming unit for converting the obtained image data into an electrostatic latent image, an electrophotographic processing unit for forming a toner image to the electrostatic latent image portion, and a control unit for controlling operation of each unit;
- wherein said electrophotographic processing unit comprises a developing agent containing a black toner having infrared reflective property, and a detector for detecting whether said toner image formed by the electrophotographic processing unit has infrared reflective property or not;
- and
- said control unit controls the operation of each unit based on the result of detection by the detector.
A copy comprising an image formed by a developing agent containing black organic pigment having infrared reflective property, said copy capable of being discriminated from a copy formed by a developing agent containing normal black organic pigment by reflecting infrared light.
