Image forming apparatus

An image forming apparatus that transfers a toner image formed on a photoconductor onto a sheet, the image forming apparatus comprising:

• a sheet conveying path along which the sheet is conveyed in a conveying direction;
• a photoconductor unit that supports the photoconductor;
• a transfer roller that is brought into pressure contact with the photoconductor via the sheet conveying path;
• a transfer unit that supports the transfer roller;
• a sheet guide that is provided between the photoconductor unit and a fixing unit and that guides the sheet along the conveying direction;
• and
• a support holder that supports the transfer unit and the sheet guide,
• wherein the support holder moves to bring the transfer unit and the sheet guide into and out of contact with the photoconductor unit and the fixing unit,
• wherein the transfer unit is provided with a transfer biasing member between the transfer unit and the support holder and is also provided with a transfer positioning part that positions the transfer unit by coming into abutment with the photoconductor unit,
• wherein the sheet guide is provided with a guide biasing member between the sheet guide and the support holder and is also provided with a guide positioning part that positions the sheet guide by coming into abutment with the fixing unit, and
• wherein the transfer unit and the sheet guide are joined to each other by an engagement part that engages the transfer unit and the sheet guide with each other.
