A printing apparatus includes a first shaft around which an adhesive sheet in which a protective sheet is provided at an adhesive layer formed at a base material is wound, a second shaft around which the protective sheet peeled off from the adhesive sheet fed out from the first shaft is wound, a driving mechanism configured to rotate the second shaft, an upper surface configured to support the adhesive sheet from which the protective sheet is peeled off and the adhesive layer is exposed, a guide portion configured to cause a fabric to pass through an upper position in a vertically upward direction of the first shaft and the second shaft and guide the fabric toward the upper surface, and a printing unit configured to perform printing on the fabric attached to the adhesive sheet in the upper surface.

A feeding device is disclosed, which comprises a paper passage, a sheet-separating roller, a friction institution, and a stopper. The sheet-separating roller is disposed in the paper passage. The friction institution is disposed in the paper passage opposite to the sheet-separating roller. The stopper is disposed in the upstream side of the sheet-separating roller. The stopper includes an axle, a short arm, and a long arm. The short arm connects to the axle, and the axle acts as a fulcrum. The long arm and the short arm disposed to the axle coaxially. A threshold of the force for pushing the short arm is larger than a threshold of the force for pushing the long arm.

An image forming apparatus includes a sheet feeding cassette, a pickup roller to feed a sheet stored in the sheet feeding cassette, a conveyance roller, an image forming portion, first and second conveyance guides, a driving motor, a torque detection unit, and a control unit. The torque detection unit detects a value related to a driving torque of the driving motor produced in a period when the pickup roller feeds the sheet. The control unit determines an image forming condition under which image formation is to be performed on the sheet at the image forming portion. The control unit determines the image forming condition in accordance with a performed result of detection by the torque detection unit performed in a period in which the sheet is guided with both the first conveyance guide and the second conveyance guide by being conveyed with the conveyance roller and the sheet is bent.

An image forming apparatus includes a first sheet feeding portion, a second sheet feeding portion, an image forming portion, a paper dust collecting portion, a merging portion, a rotatable member, a first guiding member, and a second guiding member. The paper dust collecting portion is provided downstream of the first sheet feeding portion and the second sheet feeding portion and upstream of the merging portion with respect to a conveying direction of a recording material.
