    • An image forming apparatus includes: an electrophotographic photoreceptor having a conductive substrate and a photosensitive layer provided on the conductive substrate; a charging unit for charging the electrophotographic photoreceptor; an exposure unit for exposing the charged electrophotographic photoreceptor to light thereby forming an electrostatic latent image; a developing unit for developing the electrostatic latent image with toner thereby forming a toner image; and a transfer unit for transferring the toner image from the electrophotographic photoreceptor to a transferred image-receiving medium. The exposure unit is a multi beam exposure unit which has a surface emitting laser array and which carries out the electrostatic latent image formation by scanning the electrophotographic photoreceptor with eight or more light beams where electrophotographic photoreceptor gives a quantum efficiency of 0.3 or higher when the electrophotographic photoreceptor is charged to a charged potential absolute value of 500 V and then irradiated with a monochromatic light of the same wavelength as that of the light beams to decay the charged potential absolute value to 250 V.
    • 图像形成装置包括:电子照相感光体,其具有导电性基板和设置在导电性基板上的感光层; 用于对电子照相感光体充电的充电单元; 曝光单元,用于将充电的电子照相感光体曝光,从而形成静电潜像; 显影单元,用于利用调色剂显影静电潜像,从而形成调色剂图像; 以及用于将调色剂图像从电子照相感光体转印到转印的图像接收介质的转印单元。 曝光单元是具有表面发射激光器阵列并且通过用八个或更多个光束扫描电子照相感光体来进行静电潜像形成的多光束曝光单元,其中电子照相感光体当电子照相感光体的电子照相感光体的量子效率为0.3或更高时 感光体被充电到500V的充电电位绝对值,然后用与光束相同波长的单色光照射以将充电电位绝对值衰减到250V。
