Patent ID: 7729634

Claim:
An image forming apparatus, comprising: a corona discharge type charging unit which discharges in a non-contact manner; an electrophotographic photoconductor which has an outermost surface layer containing a filler; and an airflow adjusting device which takes air from an outside of the image forming apparatus, carries the air to a vicinity of any one of the charging unit and the electrophotographic photoconductor and exhausts the air to the outside of the image forming apparatus, wherein the charging unit and the electrophotographic photoconductor are placed to face each other, the airflow adjusting device maintains ozone concentration at an average of 30 ppm or less and unevenness of the ozone concentration at 15 ppm or less at a surface of the electrophotographic photoconductor in a discharge region in an image forming area of the charging unit, and the outermost surface layer of the electrophotographic photoconductor contains a compound represented by any one of the following General Formulas (1) and (2), where R 1 and R 2 may be identical to each other or different from each other, represent any one of an alkyl group that may have a substituent group and an aryl group that may have a substituent group, at least one of the R 1 and R 2 is the aryl group that may have the substituent group, the R 1 and R 2 may be combined to each other to form a heterocyclic ring containing a nitrogen atom, and the heterocyclic ring may be further substituted by a substituent group; and Ar represents an aryl group that may have a substituent group, where R 3 and R 4 may be identical to each other or different from each other, represent an unsubstituted alkyl group or an alkyl group substituted by an aromatic hydrocarbon group, the R 3 and R 4 may be combined to each other to form a heterocyclic ring containing a nitrogen atom, and the heterocyclic ring may be further substituted by a substituent group; Ar 1 and Ar 2 represent an aryl group that may have a substituent group; “l” and “m” represent an integer of 0 to 3, and both of the “l” and “m” cannot be an integer of 0 (zero) at the same time; and “n” is an integer of 1 or 2.
