Abstract
A retaining unit retains a plurality of photosensitive drums and includes a first conveying member. A main casing has a first conveying path and a second conveying path. The first conveying path extends from a first supplying unit to a first position where a second transfer unit opposes a downstream end portion of a first transfer unit. A first transferred medium is conveyed along the first conveying path in a conveying direction. A second transferred medium extends from a second supplying unit to a second position located upstream of the first position in the conveying direction. The second transferred medium is conveyed to the first conveying path through the second conveying path. The first conveying member is configured to convey the second transferred medium supplied from the second supplying unit in the second conveying path.
Claims13
An image forming device comprising:
- a main casing;
- a retaining unit retaining a plurality of photosensitive drums juxtaposedly arrayed and spaced away from each other in an array direction, the retaining unit movable in the array direction between a mounted position in which the retaining unit is mounted in the main casing and a pulled-out position in which the retaining unit is pulled out of the main casing;
- a first transfer unit, arranged in confrontation with the plurality of photosensitive drums, to be transferred developer supported on each photosensitive drum, the first transfer unit having a downstream end portion in a mounting direction in which the retaining unit is moved from the pulled-out position to the mounted position;
- a second transfer unit disposed in confrontation with the downstream end portion to transfer the developer, which is transferred to the first transfer unit, to a transferred medium;
- a first supplying unit disposed on an opposite side of the retaining unit from the first transfer unit in a direction in which the retaining unit and the first transfer unit oppose each other, the first supplying unit configured to be supplied a first transferred medium;
- and
- a second supplying unit positioned at an upstream end portion of the main casing in the mounting direction and configured to be supplied a second transferred medium different from the first transferred medium,
- wherein the main casing has a first conveying path and a second conveying path, the first conveying path extending from the first supplying unit to a first position where the second transfer unit opposes the downstream end portion of the first transfer unit, the first transferred medium being conveyed along the first conveying path in a conveying direction, the second conveying path extending from the second supplying unit to a second position located upstream of the first position in the conveying direction, the second transferred medium being conveyed to the first conveying path through the second conveying path,
- wherein the retaining unit including a first conveying member configured to convey the second transferred medium supplied from the second supplying unit in the second conveying path.

An image forming device comprising:
- a main casing having a first conveying path and a second conveying path;
- a cartridge tray configured to support a cartridge, the cartridge tray being movable between a mounted position in which the cartridge tray is mounted in the main casing and a pulled-out position in which the cartridge tray is pulled out of the main casing;
- an intermediate belt extending in a mounting direction in which the cartridge tray is moved from the pulled-out position to the mounted position and having a downstream end portion in the mounting direction;
- a transfer roller disposed in confrontation with the downstream end portion of the intermediate belt;
- a first paper feeder configured to feed a first paper conveyed along the first conveying path in a conveying direction, the first paper feeder being disposed on an opposite side of the cartridge tray from the intermediate belt in a direction in which the cartridge tray and the intermediate belt oppose each other;
- and
- a second paper feeder configured to feed a second paper conveyed along the second conveying path, the second paper feeder being positioned at an upstream end portion of the main casing in the mounting direction,
- wherein the cartridge tray includes a conveying member configured to convey the second paper supplied from the second paper feeder in the second conveying path.
