Abstract (en)

[origin: EP2574988A2] An image forming apparatus (100) includes a transfer device separator (70; 170; 270) that moves a transfer device (22) between a contact position where the transfer device (22) contacts a toner image carrier (10) and a first isolation position where the transfer device (22) is isolated from the toner image carrier (10) with a first interval (D1) therebetween. The transfer device (22) is at the contact position as first to third toner images (T1, T2, T3) and a blank section (S2) between the first toner image (T1) and the second toner image (T2) carried by the toner image carrier (10) pass through a transfer region (N) and at the first isolation position as a toner patch section (S1) between the first toner image (T1) and the second toner image (T2) carried by the toner image carrier (10) passes through the transfer region (N).
