Image forming apparatus
An image forming apparatus includes a transport belt, a first intermediate transfer belt, and a second intermediate transfer belt. The transport belt is disposed along a transport path extending in a vertical direction. The transport belt is configured to transport a recording medium while coming into contact with one surface of the recording medium. The first intermediate transfer belt is configured to sandwich the recording medium together with the transport belt. An image is transferred from the first intermediate transfer belt to the recording medium. The second intermediate transfer belt is disposed above the first intermediate transfer belt. The second intermediate transfer belt is configured to sandwich, together with the transport belt, the recording medium which is in a state where the recording medium is sandwiched between the first intermediate transfer belt and the transport belt. An image being transferred from the second intermediate transfer belt to the recording medium.
1. An image forming apparatus comprising:
plural image forming bodies each comprising
plural image forming sections, and
a primary intermediate transfer body onto which images formed by the plural image forming sections are primarily transferred;
plural secondary transfer units provided on the plural image forming bodies, respectively, the secondary transfer units being configured to sequentially and secondarily transfer the images of the primary intermediate transfer bodies in a recording medium transport direction; and
a charge removal unit disposed between the plural secondary transfer units, the charge removal unit being configured to remove a charge of a recording medium charged in any of the secondary transfer units.
2. The image forming apparatus according to claim 1 , further comprising:
a transport belt configured to transfer the recording medium to the plural secondary transfer units, wherein
the transport belt is formed in an annular shape,
the transport belt transfers the recording medium while an outer peripheral surface of the transport belt comes into contact with one surface of the recording medium,
the charge removal unit is disposed inside the transport belt, and
the charge removal unit removes a charge of the recording medium via the transport belt.
3. The image forming apparatus according to claim 2 , wherein the charge removal unit is a driven roller that is in contact with an inner peripheral surface of the transport belt and is driven and rotated by the transport belt.
4. The image forming apparatus according to claim 1 , wherein
a transport belt transports the recording medium from a lower side to an upper side in a gravitational direction, and
a first intermediate transfer belt and a second intermediate transfer belt overlap with each other vertically in the gravitational direction.
5. The image forming apparatus according to claim 1 , wherein the charge removal unit applies, to the recording medium, a charge having an opposite polarity to that of the recording medium charged at a first transfer position, by being applied a voltage.
6. The image forming apparatus according to claim 5 , further comprising:
a receiving unit configured to receive information on the recording medium, wherein
a voltage applied to the charge removal unit is changed based on the information received by the receiving unit.
7. The image forming apparatus according to claim 1 , wherein
the charge removal unit is provided on a non-image surface side that is opposite to an image surface of the recording medium, and
the charge removal unit is controlled so that when the recording medium has a high resistance, the charge removal unit executes charge removal.
