Patent ID: 7962055

Claim:
An image forming apparatus comprising: a photoreceptor; a charging unit that includes: a charger that contacts with a surface of the photoreceptor and charges the surface to a first voltage; and a static eliminator that contacts with the surface and discharges the surface from the first voltage to a second voltage; an exposure unit that exposes the surface which is charged to substantially the second voltage; a developing unit that supplies a toner to the surface so as to form a visible toner image on the surface; a transfer unit that transfers the visible toner image formed on the surface to a recording medium; a fixing unit that fixes the visible toner image on the recording medium; an environment detecting unit that detects an environmental data; and a control unit that controls the first voltage based on the environmental data, wherein the environmental data includes a temperature value detected by the environment detecting unit, and wherein the control unit controls the first voltage to be greater in absolute value by 100 V or more when the temperature value is 21° C. or less.
