摘要： A method of developing an electrostatic latent image wherein an electrostatic latent image with a negative polarity is formed on an organic photoreceptor and developed with a toner bearing a positive electric charge. The toner used to develop the latent image includes a binder resin, a coloring agent, silica, zinc stearate, and at least one oxide selected from hydrophobic aluminum oxide and hydrophobic titanium oxide. This method of developing the electrostatic latent image produces an image having a higher maximum image density.
