DELIVERY DEVICE AND IMAGE FORMING APPARATUS
A delivery device includes a container that contains pressure sensitive adhesive particles that contain at least a binder resin, have a sulfur content of 0.1 mass % or more and 0.5 mass % or less relative to a total of the pressure sensitive adhesive particles as measured by X-ray fluorescence, and have a pressure-induced phase transition property, the container having a shape of a cylinder having a spiral recessed or projecting portion on an inner peripheral surface thereof; and a transmitting unit to which a rotary drive force from a driving unit that rotates the container is transmitted, the transmitting unit being disposed in the container.
1 . A delivery device comprising:
a container that contains pressure sensitive adhesive particles that contain at least a binder resin, have a sulfur content of 0.1 mass % or more and 0.5 mass % or less relative to a total of the pressure sensitive adhesive particles as measured by X-ray fluorescence, and have a pressure-induced phase transition property, the container having a shape of a cylinder having a spiral recessed or projecting portion on an inner peripheral surface thereof; and
a transmitting unit to which a rotary drive force from a driving unit that rotates the container is transmitted, the transmitting unit being disposed in the container.
2 . The delivery device according to claim 1 , wherein the pressure sensitive adhesive particles have at least two glass transition temperatures, and a difference between the lowest glass transition temperature and the highest glass transition temperature is 30° C. or more.
3 . The delivery device according to claim 1 , wherein the binder resin contains a styrene resin that contains a styrene and another vinyl monomer as polymerization components, and a (meth)acrylate resin that contains at least two (meth)acrylates as polymerization components, wherein a mass ratio of the (meth)acrylates relative to a total of the polymerization components of the (meth)acrylate resin is 90 mass % or more.
4 . An image forming apparatus comprising:
the delivery device according to claim 1 , the delivery device delivering pressure sensitive adhesive particles; and
an image forming unit that forms an image by using the pressure sensitive adhesive particles delivered by the delivery device.
