Abstract
An image forming system includes a conveying member which conveys a sheet along a conveying direction; and a separation device which separates the sheet from the conveying member at a separation position. The separation device includes an air flow generating part and a duct. The air flow generating part generate an air flow. The duct which blows the air flow generated by the air flow generation part, from a position above the sheet to a downstream side in the conveying direction at the separation position.
Claims4
An image forming system comprising:
- a conveying member which conveys a sheet along a conveying direction;
- and
- a separation device which separates the sheet from the conveying member at a separation position, wherein
- the separation device includes:
- an air flow generating part which generates an air flow;
- a duct which blows the air flow generated by the air flow generation part, from a position above the sheet to a downstream side in the conveying direction at the separation position;
- and
- a duct guide which guides the air flow passed through the duct in the conveying direction above the sheet.

An image forming system comprising:
- a conveying member which is an endless belt having a large number of through-holes penetrating in a thickness direction, and conveys a sheet along a conveying direction;
- a suction device which generates a negative pressure in the through-holes to attract the sheet to the conveying belt is provided;
- a separation device which separates the sheet from the conveying member at a separation position;
- rollers spaced apart in the conveying direction and around which the conveying member is wound;
- and
- a conveying plate disposed to face an inner surface of the conveying member, wherein
- the separation device includes:
- an air flow generating part which generates an air flow;
- and
- a duct which blows the air flow generated by the air flow generation part, from a position above the sheet to a downstream side in the conveying direction at the separation position,
- the separation position is a position between the roller disposed on a downstream side in the conveying direction and a downstream end portion of the conveying plate, and
- the suction device is not provided at the separation position, and a force for attracting the sheet to the conveying belt at the separation position is lower than that at other positions or zero.

An image forming system comprising:
- a conveying member which conveys a sheet along a conveying direction;
- and
- a separation device which separates the sheet from the conveying member at a separation position, wherein
- the separation device includes:
- an air flow generating part which generates an air flow;
- and
- a duct which blows the air flow generated by the air flow generation part, from a position above the sheet to a downstream side in the conveying direction at the separation position, wherein
- the duct includes an upstream part extending downward from an inlet opening and a downstream part inclined toward an outlet opening to a downstream side in the conveying direction, and
- the downstream part is formed so that a cross-sectional area gradually narrows toward the outlet opening, and a lower plate of the downstream part is inclined slightly upward toward the outlet opening.
