Abstract:
A development device, comprising:a charging section having an electron emission section and applying electrons generated in the electron emission section due to a photoelectric effect to a developer so as to charge the developer; an irradiation section for irradiating the electron emission section with light so as to cause the electron emission section to generate the electrons; a developer carriage section for holding the developer thus charged, and performing carriage of the developer to a latent image holding body having an electrostatic latent image on a surface; and a control section for performing control of (a) application of a voltage to the irradiation section, (b) application of a voltage to the electron emission section, (c) application of a voltage to the developer carriage section, and (d) beginning of the carriage of the developer by the developer carriage section, at predetermined timings, respectively, the electrostatic latent image on the latent image holding body being developed by the developer which has been charged.
