Abstract
The present invention provides an image forming apparatus and an image forming method capable of preventing excessive charging in the toner within the cleaning device for effectively preventing generation of the black spots derived from the leak current. In the image forming apparatus comprising a cleaning device having a cleaning blade for scraping out the toner on a latent image carrier body surface and the image forming method using the same, the toner contains a titanium oxide as an additive agent, and with the premise that the fluorescence X ray intensity of the titanium oxide added to the toner before use is X1, and the fluorescence X ray intensity of the titanium oxide added to the toner within the cleaning device is X2, X1 and X2 satisfy the following relationship formula (1):X2/X1≧1.2 (1).
