Image forming apparatus

摘要

In accordance with one embodiment, an image forming apparatus includes an image forming section and a transfer roller. A support body supports the image carrier in a main body opposite to the transfer roller. A holding member positioned in the support body holds the transfer roller. The holding member includes at least one groove in a portion of the holding member that holds the transfer roller. At least one conductive member is positioned in, and protruding from, the at least one groove so that a part of the conductive member makes electrical contact with the transfer roller when the transfer roller is held in the holding member. A power supply section applies transfer bias between the image carrier and the transfer roller through the conductive member.

主权项

1. An image forming apparatus, comprising:
an image forming section configured to form an image on an image carrier; a transfer roller configured to transfer the image formed on the image carrier to an image receiving medium; a support body configured to support the image carrier in a main body opposite to the transfer roller; a holding member positioned in the support body and configured to hold the transfer roller, the holding member having a U-shaped holding arm and including at least two grooves in a portion of the holding member that holds the transfer roller, the at least two grooves facing each other on the holding arm; at least one conductive member having at least two curved portions, each positioned in, and protruding from, a different one of the at least two grooves towards an inside of the holding arm so that a part of the conductive member makes electrical contact with the transfer roller when the transfer roller is held in the holding member; and a power supply section configured to apply transfer bias between the image carrier and the transfer roller through the conductive member.
