Title:
DEVICE FOR MEASURING ELECTROSTATIC CHARGE AMOUNT OF TONER AND METHOD FOR MEASURING DISTRIBUTION OF ELECTROSTATIC CHARGE AMOUNT OF TONER
Document Type and Number:
Japanese Patent JP2009150948
Kind Code:
A
Abstract:
To provide devices for measuring an electrostatic charge amount of toner and methods for measuring distribution of an electrostatic charge amount of toner enabling a precise measurement without damaging developing rollers even when applied to one-component developers.
The device for measuring the electrostatic charge amount of toner has: a hollow toner suction port 1 for sucking the toner T from a toner substrate 3; and a means 4 for measuring electrostatic charge amount of the sucked toner T. The toner suction port 1 forms a hermetically sealed space with the toner substrate 3.
