Abstract
Provided is an image forming apparatus for forming a toner image including: a first light source emitting a beam corresponding to image information; a first photosensitive member; a first developing means for developing a latent image with a first toner; a second light source; a second photosensitive member; and a second developing means for developing a latent image with a second toner, in which the coloring agent contained in the first toner and the coloring agent contained in the second toner are substantially of the same hue, with the content of the coloring agent contained in the second toner being smaller than the content of the coloring agent contained in the first toner, and in which an oscillation wavelength of at least the first light source ranges from 370 to 500 nm. With the image forming apparatus structured as described above, an improvement in terms of granularity is achieved.
