Liquid development device and image-forming apparatus

摘要

A liquid development device includes a storage section storing a liquid developer in which toner is dispersed, a development member to which the liquid developer stored in the storage section is applied using an application unit, a removing device that, after an electrostatic latent image in a latent image-holding member is developed, removes the liquid developer remaining in the development member, and a shearing device that is provided in a path through which the liquid developer removed using the removing device is returned to the storage section, and applies a shear force to the liquid developer by making the liquid developer pass through a contact section of two members either or both of which rotate and that have different circumferential velocities from each other.

1. A liquid development device comprising:
a storage section storing a liquid developer in which toner is dispersed; a development member to which the liquid developer stored in the storage section is applied using an application unit; a removing device that, after an electrostatic latent image in a latent image-holding member is developed, removes the liquid developer remaining on the development member; and a shearing device that is provided in a path through which the liquid developer removed using the removing device is returned to the storage section, and applies a shear force to the liquid developer by making the liquid developer pass through a contact section of two members both of which rotate and that have different circumferential velocities from each other,
wherein the two members move in the same direction at different circumferential velocities in the contact section, andwherein the shearing device includes a first roll and a second roll, the first roll and the second roll having a first protrusion section and a second protrusion section, which protrude toward an outside of a radial direction, on circumferential surfaces respectively, the first protrusion section and the second protrusion section being alternately disposed in an axial direction, and engage with each other.
