What is Printer Toner?
In earlier machines toner was poured by the user from a bottle into a reservoir in the machine. Modern machines feed directly from a cartridge. Empty cartridges are often refilled by third party vendors.
As a fine powder, toner can remain suspended in the air for some period, and is considered to have health effects comparable to inert dust. It can be an irritant to people with respiratory conditions such as asthma or bronchitis. Following studies on bacteria in the 1970s that raised concerns about health effects resulting from pyrol, a contaminant created during manufacture of the carbon black used in toner, manufacturing processes were changed to eliminate pyrol from the finished product.
Toner can be washed off of skin or garments with cold water. Hot or warm water will soften the toner, causing it fuse to the material it is on. Toner fused to skin will wear off in time, or can be partially removed using abrasive hand cleaners. Toner fused to clothing cannot usually be removed.

Toner is a special type of ink used by copy machines and laser printers. Toner consists of a dry, powdery substance that is electrically charged so that it adheres to a drum, plate, or piece of paper charged with the opposite polarity. For most laser printers, the toner comes in a cartridge that you insert into the printer. When the cartridge is empty, you can replace it or have it refilled. Typically, you can print thousands of pages with a single cartridge.
Toner has traditionally been made by compounding the ingredients and creating a slab which was broken or pelletized and then turned it into a fine powder with a controlled particle size range by air jet milling. This process resulted in toner granules that, if viewed under a microscope, showed varying sizes and jagged shapes. To get a finer print, some companies are using a chemical process to grow toner particles. This results in more uniform size and shapes of toner particles. The resulting smaller uniform shapes permit more accurate color reproduction and more efficient toner use.
