Image forming apparatus which can optimize cleaning time of transfer member contacting inter-image area of image bearing member

摘要

A toner removing means (70) applies a cleaning electric field for transferring residual toner from a transfer member (26) back to an image bearing member (28) in an image forming apparatus. In the case that a detection toner image is formed in an inter-image area on an image bearing member (28), the cleaning electric field is applied for a time T1 > T2, where T2 is the time of application of said field if no detection toner image is formed.
