Filed: 1989-11-17
Abstract: PURPOSE:To prevent toner from being splashed due to a magnetic field generated in the vicinity of a transfer part and to obtain an effective image by constituting a transfer means of a member for reducing a resistance value by pressure. CONSTITUTION:A transfer roll 2 is constituted of forming a layer 2b consisting of solid-like or sponge-like pressure conductive rubber around a core bar 2a connected to a power supply 3. The pressure conductive rubber to be a composite material combining metals with silicone rubber is in an insulating state whose resistance value is >=10MOMEGA in a natural state, but the resistance is turned to a conductive state <= several-tensOMEGA by applying pressure to the material. Since the transfer roll 2 is constituted of such a material and the resistance value of a part A is sharply reduced by pressing the roll 2 against a photosensitive body 1, a bias voltage is impressed to the core bar 2a so that a transfer current of about 0.4 to 0.5muA is allowed to flow to obtain effective transfer efficiency in such a state.

CONSTITUTION: At first, a servo motor is driven at a constant speed and a torque required for constant speed operation is measured and then torques F, G required for canceling the frictional component and the gravitational component, respectively, are determined. The servo motor is accelerated and a torque command Tc to be applied is determined and then the time variation of torque T required for acceleration drive is determined. Subsequently, time variation of the acceleration in acceleration drive is determined based on the measurements thus determining the relationship between the speed (v) and the torque T based on the time variation of torque T required for the acceleration drive and the time variation of the speed, and the relationship between the speed (v) and the acceleration A based on the time variation of acceleration.  Finally, a torque TJ required for accelerating the inertia is determined according to a formula; TJ=T-F-G, and then it is divided by the acceleration A to determine an inertia J.
