Title:
IMAGE FORMING APPARATUS AND PROCESS CARTRIDGE
Document Type and Number:
Japanese Patent JP2023144997
Kind Code:
A
Abstract:
To provide an image forming apparatus that prevents slip-through of a removed object from a cleaning blade after continuously forming images.SOLUTION: An image forming apparatus comprises: an electrophotographic photoreceptor; an electrifying device; an electrostatic charge image forming device; a developing device that stores developer including toner and forms a toner image; a cleaning device having a cleaning blade that cleans a surface of the electrophotographic photoreceptor; and a transfer device that transfers the toner image to a surface of a recording medium. The toner has a toner particle including a binder resin and resin particles, and an external additive. An impact modulus of elasticity A and a 100% modulus B of a member constituting a contact part of the cleaning blade in contact with the electrophotographic photoreceptor, and a content ratio C of the resin particles to all toner particles satisfy the following formula (1) and the following formula (2). Formula (1): 0.045≤content ratio C of resin particles/impact modulus of elasticity A≤1.160. Formula (2): 0.29≤content ratio C of resin particles/100% modulus B≤4.53.SELECTED DRAWING: Figure 1
