Abstract
An image forming device includes a development section which has a blade for applying electrons generated in its photoelectric surface due to a photoelectric effect to a toner so as to charge the toner; an ultraviolet irradiator for irradiating the photoelectric surface with light; a development roller for holding the toner thus charged, and performing carriage of the toner to a photoconductive drum having an electrostatic latent image on a surface; wherein the electrostatic latent image on the photoconductive drum is developed by the charged toner. The development section further includes a control section for performing control of application of a voltage to the ultraviolet irradiator, application of a voltage to the photoelectric surface, application of a voltage to the development roller, and beginning of the carriage of the toner by the development roller, at predetermined timings, respectively.
