IPC: G03G15/02
Filed: 1998-09-11
Abstract: PROBLEM TO BE SOLVED: To make it possible to apply lubricant to the surface of an image carrier from an electrifying member without causing wear in the electrifying member such as an electrifying roller. SOLUTION: Wear in the electrifying roller 10 is prevented by making the electrifying roller 10 rotate accompanying the rotation of the photoreceptor drum 1 by the torque of the drum 1, thereby preventing slide contact between the electrifying roller 10 and the photoreceptor drum 1. Also, even when the electrifying roller 10 and photoreceptor drum 1 become equal in linear velocity due to the accompanying rotation, a voltage to be applied to a part of the electrifying roller 10 which corresponds with an image non-formation area is set to 0 V (off), thereby causing the lubricant 7 to be transferred smoothly from the electrifying roller 10 to the photoreceptor drum 1. Thus, the lubricant 7 is sufficiently applied to the surface of the photoreceptor drum 1 and cleaning performance is improved.

Abstract: PROBLEM TO BE SOLVED: To prevent a supplementary liquid from being dispersed uselessly from a supplementary case by providing a supplementary case with a supplementary liquid supply part having an opening for delivering the supplementary liquid and locating the upper end at the flow-in opening of a supplementary liquid receiving part lower than the lower end at the flow-out opening of the supplementary case thereby simplifying supply of the supplementary liquid. SOLUTION: Since the upper end 33 at the flow-in opening 32 of a supplementary liquid receiving part 30 is located slightly lower than the flow-out opening 36 of a supplementary case 24, supply of supplementary ink liquid is interrupted when it reaches a liquid level 25 slightly higher than the upper end 33. Since the supplementary ink liquid is supplied from the supplementary case 24 when the liquid level 25 in a supplementary case 23 drops, a constant liquid level 25 can be sustained at all times. Since the liquid level 25 in the supplementary case 23 is slightly higher than the upper end 33 at the flow-in opening 32, it is not opened to the atmosphere. Since the supplementary ink liquid in the supplementary case 23 is not evaporated into the atmosphere, useless dispersion of the supplementary ink liquid can be suppressed.
