IMAGE FORMING APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18506049 titled 'IMAGE FORMING APPARATUS

Simplified Explanation

The patent application describes an image forming apparatus with specific parameters related to the adhesion forces between toner particles, carrier particles, and the image bearing member.

• Rotatable image bearing member
• Rotatable developing member carrying developer made of toner particles and carrier particles
• Pressing force (F1) pressing the developing member against the image bearing member
• Total number of carrier particles (N1) interposed between toner particles and the image bearing member
• Adhesion force (Ft) between a carrier particle and a toner particle
• Adhesion force (Fdr1) between a carrier particle and the image bearing member
• Requirement: Ft ≤ Fdr1

Original Abstract Submitted

An image forming apparatus includes a rotatable image bearing member and a rotatable developing member to carry developer made up of toner particles and carrier particles adhered to surfaces of the toner particles. Where a pressing force pressing the developing member against the image bearing member is F1, a total number of the carrier particles interposed between the toner particles and the image bearing member is N1, and an adhesion Ft between a carrier particle and a toner particle, measured when the carrier particle is pressed against the toner particle with F1/N1 that is a pressing force per unit carrier particle, and an adhesion Fdr1 between the carrier particle and the image bearing member, measured when the carrier particle is pressed against the image bearing member with F1/N1, satisfy Ft≤Fdr1.
