The invention provides a printing consumable for a toner cartridge, the printing consumable comprising the following raw materials by weight: 0.5-1 part of tungsten carbide powder, 2-6 parts of indiumtin oxides, 2-6 parts of cadmium sulfide, 0.1-0.5 part of nickel, 1-3 parts of nickel oxides, and 2-6 parts of organic photoelectric conversion materials. The organic photoelectric conversion materials have a structural formula represented by the formula (I). The organic printing consumable used in the present application has a large number of aromatic hydrocarbon structures; and a large number of orbits contained therein not only can achieve good light guiding performance, but also can effectively assist in forming a large number of excitons, thereby improving the printing effect.
