IMAGE FORMING APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240288797 titled 'IMAGE FORMING APPARATUS
The image forming apparatus described in the abstract includes various components such as an image bearing member, a toner image forming portion, a transfer member, a voltage applying portion, an acquiring portion, and a controller.
- The controller is responsible for controlling the transfer member cleaning operation during continuous printing, where toner images are transferred onto different recording materials.
- In the case that the first recording material is identified as an envelope based on recording material information, the controller ensures that a specific cleaning operation is executed after the first recording material passes through the transfer portion and before the second recording material reaches the transfer portion.
- This cleaning operation involves applying a first cleaning voltage of the same polarity as the normal charge polarity of toner and a second cleaning voltage of an opposite polarity to the normal charge polarity of the toner alternately by the voltage applying portion.
- By carrying out this cleaning operation in a specific sequence, the apparatus can maintain the quality of transferred images and prevent any potential issues related to toner residue or contamination.
- Overall, this innovation in the image forming apparatus aims to improve the efficiency and reliability of the printing process, especially when dealing with different types of recording materials.
Potential Applications: - Printing industry - Office environments - Commercial printing services
Problems Solved: - Ensuring clean and accurate image transfer - Preventing toner contamination on different recording materials
Benefits: - Enhanced print quality - Reduced maintenance requirements - Improved overall printing efficiency
Commercial Applications: Title: Enhanced Image Transfer Cleaning System for Printing Devices This technology can be utilized in various commercial printing services, office environments, and any industry that requires high-quality image printing on different recording materials.
Questions about the technology: 1. How does the controller determine the type of recording material being used for printing? 2. What are the potential long-term benefits of implementing this cleaning operation in image forming apparatus?
Original Abstract Submitted
an image forming apparatus includes an image bearing member; a toner image forming portion, a transfer member, a voltage applying portion, an acquiring portion, and a controller. in continuous printing in which toner images are continuously transferred onto a first recording material and a second recording material, in a case that the first recording material is an envelope on the basis of recording material information, the controller carries out control so that a transfer member cleaning operation in which a first cleaning voltage of the same polarity as a normal charge polarity of toner and a second cleaning voltage of an opposite polarity to the normal charge polarity of the toner are alternately applied by the voltage applying portion is executed after the first recording material passes through the transfer portion and before the second recording material reaches the transfer portion.
