This abstract first appeared for US patent application 20240411241 titled 'IMAGE FORMING APPARATUS




==Original Abstract Submitted==

an image forming apparatus includes a non-magnetic one-component developer, an image bearing member, and a development device that develops an electrostatic latent image formed on a surface of image bearing member by supplying non-magnetic one-component developer to the electrostatic latent image. development device includes a development roller that carries non-magnetic one-component developer and a restricting member that restricts the thickness of a development layer constituted by non-magnetic one-component developer. non-magnetic one-component developer contains a positively chargeable toner containing toner particles that include toner mother particles and external additive particles attached to the surfaces of toner mother particles and including resin particles and silica particles. when toner undergoes ultrasonic treatment that involves applying ultrasonic vibration at a frequency of 28 khz and an output of 100 w for 5 minutes, resin particles and silica particles have detachment fractions within a range of 18% to 42%, and 5% to 25%, respectively.
