What is the function of the fuser in a laser printer?
A copier or laser printer uses dry ink called toner, a fine plastic powder, to create an image. The toner is selectively placed on a light-sensitive surface which has been exposed to the image to be copied. It is then transfered to paper. At this point it is just loose dust on the surface of the paper and could be easilly brushed off.
The paper with the toner on it passes between heated rollers which press the toner into the paper and melt it at the same time. The result is an image permanently fixed to the paper.
The heated roller is the Fuser, because it fuses the toner to the paper.

This is a big difference from the offset printing that my grandfather used for his printing business. He would put together individual letters and blocks with engraved pictures where they would be run in his press with ink rollers applying ink directly to the type. That is a simplified description, but the set up for offset printing was time consuming and relatively expensive.

What creates images using a laser beam and powdered ink?
The answer given below is very incomplete and not entirely accurate, so I will explain more fully.
To start, the print job that is sent to the printer is converted into a digital image that is fed to the laser assembly. This causes the printer to scan its beam back and forth across the surface of the image drum so as to give it a minor positive charge where there is to be toner. The drum then passes through the toner reservoir in which the toner is negatively charged. The toner then sticks to the positively charged areas of the image. While all this is going on, the paper is being fed from the paper tray and across either a corona wire or, more commonly, the charging roller. (This is the foam roller in the first part of the paper path. Do not touch this with your bare hands because the oils from your hands will disrupt its ability to hold its static charge and transfer it to the paper, thus causing print quality problems). As the paper passes under the image drum, the drum rotates so that each part of the paper receives the image intended for it. This is achieved by the paper having a stronger positive charge than the image drum and, thus, the toner is more strongly attracted to it. After this, the paper continues to move through the printer into the fusing assembly (sometimes simply referred to as the fuser). This is the heat-producing part located toward the back of the printer. With its optimal temperature of about 350 degrees Fahrenheit (about 177 degrees Celsius), it melts the dry plastic powder that is the toner and bonds it to the paper. At this point, the paper is finally ready for expulsion and is fed to the output assembly and falls into the output tray, ready for your review and use.
