Abstract:
1. An image forming apparatus comprising: plural image forming units that form respective color visible images by electrostatically applying different color developers onto respective color image holders; a belt transfer member, in contact with the respective color image holders, to sequentially overlay-transfer the developers applied on the image holders of the image forming units; intermediate transfer electrode members, positioned on an opposite side to the image holders of the image forming units, via and in contact with the belt transfer member, that receive application of a primary transfer voltage so as to electrostatically transfer the images from the image forming units onto the belt transfer member; and a paper transfer electrode member, positioned on an opposite side to a backup member, via and in contact with the belt transfer member, that receives application of a secondary transfer voltage so as to transfer the visible images transferred on the belt transfer member onto a print sheet at a time, wherein the primary transfer voltage is applied to the plural intermediate transfer electrode members from one power source.
