Image forming apparatus and image forming method

摘要

The invention prevents the phenomenon of occurrence of toner scattering or density fluctuations by changing the appropriate transfer conditions according to the toner charge of the toner images formed on an intermediate image transfer member. The density of toner images formed under prescribed image forming conditions on an intermediate image transfer member is detected, the toner charge is obtained from the detected density, and the pre-transfer charging section is controlled according to the obtained toner charge.
