  • Patent number: 11934145
    Abstract: A developing apparatus includes an electrostatic latent image bearer, a developing sleeve, a case, and an air filter. The case accommodates a two-component developer and the developing sleeve. The air filter is attached to the case. The air filter has a thickness of 2 to 20 mm and has a density gradient with a pressure loss of 2 to 40 Pa at a wind speed of 10 cm/s. The air filter forms an airflow sucked into the case from a gap between the developing sleeve and the case and forms an airflow discharged from the case through the air filter. The two-component developer accommodated in the case contains a magnetic particle a surface of which is coated with a resin layer. The resin layer contains at least one type of chargeable particle.

  • Publication number: 20220346492
    Abstract: A shoe sole that is less likely to feel push-up on the sole at the time of landing and suppresses pronation to enable quick weight movement in running or jogging, while being widely available in sports requiring weight movement such as golf, tennis, basketball, soccer, and skateboarding, as well as that is lightweight, has good wearing comfort and provides stable walking even in using on the street or walking. The shoe sole includes a shoe sole main body made of a flexible material, and a plate made of a material having a flexural modulus higher than a flexural modulus of the flexible material constituting the shoe sole main body, in which at least two of the plates are included in the shoe sole main body.
