The secondary transfer belt (331) presses against the intermediate transfer belt (311) in a secondary transfer region (92).

The auxiliary member (33) is disposed on the secondary transfer roller (332) side of the secondary transfer belt (331), upstream of the secondary transfer roller (332) in the paper feed direction (93).

The apparatus comprises a primary transfer device (150) and secondary transfer device (100).

A toner layer directly deposited on the intermediate transfer has a higher potential, and is therefore easy to secondary-transfer to thereby enhance a secondary transfer efficiency and a reproducibility of secondary colors.

The sub-transfer line (30) is arranged as a transfer system independent from the main transfer line (20).

The setting unit (24) sets a primary transfer mode or a secondary transfer mode as the transfer mode.

The secondary transfer roller (332) is opposite the drive roller (312), with the intermediate transfer belt (311) and the secondary transfer belt (331) therebetween, and is electrically grounded.

The secondary transfer device (100) includes a secondary power transformer (202) having a set of windings (106) and a a secondary data transformer (204) having a set of windings (112).

Energy, such as power and data, is transferred from the primary transfer device (150) to the secondary transfer device (100).

This makes it possible to prevent a transfer failure due to the lack of primary transfer electric field at a primary transfer portion when secondary transfer is performed to the recording material.

As a result, the present invention is intended to prevent the leading end of the recording material which enters the secondary transfer nip from distorting the toner image on the intermediate transferring member.

An input driving transfer gear (3) drives the driven input transfer gear (5) and secondary transfer gear (7) drives an orbital driven gear (9) and the balancing drive gear system (40).

An earth electrode member such as an earth roller in contact is disposed on the upstream side of a form transfer roller for secondary transfer on a form from an intermediate transfer belt.

But the biggest challenge is transportation between the warehouse and the aircraft.

A manifold main housing (61) contains a purge valve (41) and two three-way solenoids (37, 39) controlling respectively a secondary transfer valve (43) and a pilot nozzle transfer valve (45).
