Image forming apparatus

An image forming apparatus comprising:

• a transfer unit configured to form a transfer nip portion for nipping and conveying a sheet and to transfer an image to the sheet;
• a fixing unit provided downstream of the transfer unit in a sheet conveyance direction and configured to form a fixing nip portion for nipping and conveying a sheet and to fix the image transferred to the sheet by the transfer unit;
• a first belt suction conveyance unit provided between the transfer unit and the fixing unit in the sheet conveyance direction and configured to suck a sheet onto a first belt and convey the sheet;
• and
• a second belt suction conveyance unit provided between the first belt suction conveyance unit and the fixing unit in the sheet conveyance direction and configured to suck a sheet onto a second belt and convey the sheet,
• wherein the fixing nip portion is arranged at a position above the transfer nip portion,
• wherein, in the sheet conveyance direction, an upstream end portion of the first belt in the first belt suction conveyance unit is provided below the transfer nip portion, a downstream end portion of the first belt in the first belt suction conveyance unit is provided above an upstream end portion of the second belt in the second belt suction conveyance unit, and a downstream end portion of the second belt in the second belt suction conveyance unit is provided below the fixing nip portion, and
• wherein the first belt in the first belt suction conveyance unit and the second belt in the second belt suction conveyance unit are inclined from a lower position to an upper position from upstream to downstream in the sheet conveyance direction.
