IMAGE FORMING APPARATUS AND CONTROLLING METHOD OF THE SAME
First Claim
1. An image forming apparatus which can perform printing using a plurality of color materials including a black color material comprising:
- a controller section that executes image processing on data of an image to be outputted; and
a printing execution unit that forms the image on a printing medium on the basis of the image-processed output data transferred from the controller section;
the controller section comprising;
a color-material counting section that measures the quantities in which the respective color materials of the plurality of colors are consumed on the basis of the output data; and
a determination section that acquires the measured values from the color-material counting section for each specified output unit, and determining that printing was conducted in color for the specified output unit when the measured values of the color materials other than the black color material have changed and that printing was conducted in monochrome for the specified output unit when the measured value of the black color material alone has changed.

Abstract
An image forming apparatus includes a controller section that executes image processing on data of an image to be outputted, and a printing execution unit that forms the image on a printing medium on the basis of the image-processed output data transferred from the controller section; the controller section including a color-material counting section that measures the quantities in which the respective color materials of the plurality of colors are consumed on the basis of the output data; and a determination section that acquires the measured values from the color-material counting section for each output unit, and determining that printing was conducted in color for the output unit when the measured values of the color materials other than the black color material have changed and that printing was conducted in monochrome for the output unit when the measured value of the black color material alone has changed.

6. A method for controlling an image forming apparatus which can perform printing using a plurality of color materials including a black color material having a controller section for executing image processing on data of an image to be outputted, and a printing execution unit for forming the image on a printing medium on the basis of the image-processed output data transferred from the controller section comprising:
-
counting the color materials by measuring the quantities in which the respective color materials of the plurality of colors are consumed on the basis of the output data; and making a determination by acquiring values measured in the color-material counting for each specified output unit, and determining that printing was conducted in color for the specified output unit when the measured values of the color materials other than the black color material have changed and that printing was conducted in monochrome for the specified output unit when the measured value of the black color material alone has changed.
