IMAGE FORMING APPARATUS AND IMAGE FORMING METHOD
First Claim
1. An image forming apparatus comprising:
- at least one photoconductor;
a light source to expose the at least one photoconductor; and
circuitry to;
receive first image data and tag data, the first image data including first pixels each indicating density of an image to be formed or one of turning on the light source and turning off the light source, the tag data indicating an attribute of each of the first pixels;
set specific data to identify a first target pixel subjected to change out of the first pixels;
convert the first image data into second image data including second pixels, the second image data having a higher resolution than a resolution of the first image data; and
control the light source according to the second image data to form the image,in conversion of the first image data into the second image data, the circuitry identifying a second target pixel corresponding to the first target pixel out of the second pixels of the second image data according to the specific data and the tag data, and changing the second target pixel into a pixel to turn on the light source, so as to generate the second image data.

Abstract
An image forming apparatus includes a photoconductor, a light source, and circuitry that receives: first image data including first pixels each indicating image density or one of turning on and off the light source; and tag data indicating an attribute of each first pixels. The circuitry sets specific data to identify a first target pixel subjected to change out of the first pixels, converts the first image data into second image data having a higher resolution than that of the first image data, and controls the light source according to the second image data to form an image. In conversion, the circuitry identifies a second target pixel corresponding to the first target pixel out of second pixels of the second image data according to the specific data and the tag data, and changes the second target pixel into a pixel to turn on the light source.
