摘要： The present invention provides an image forming method comprising: electrostatically charging a chargeable member for supporting thereon an electrostatic image by a contact charging assembly; forming an electrostatic image on the chargeable member; developing the electrostatic image on the chargeable member to form a toner image with a toner comprising a styrene binder resin an a coloring agent, wherein an aldehyde is contained in said toner in an amount of not more than 0.005% by weight based on the weight of the toner; transferring the toner image to a transfer paper; and fixing the toner image on the transfer paper by applying heat and pressure to the toner image.

摘要： An image forming apparatus includes a member to be charged for carrying an electrostatic image, a contact-charging means for charging the member to be charged in contact with the member to be charged, and a developing means for developing the electrostatic image carried on the member to be charged. The developing means includes a developer for developing the electrostatic image comprising a toner and hydrophobic inorganic fine powder. The hydrophobic inorganic fine powder not only improves the fluidity of the developer and adjusts the chargeability of the developer but also prevents difficulties due to interaction between the member to be charged and the contact charging means in the presence of residual developer, such as damages of the member to be charged and toner-sticking onto the member to be charged.

摘要： An image forming apparatus is constituted by an image-bearing member for bearing a latent image, and a developing apparatus for developing the latent image. The developing apparatus is constituted by a developer container for containing a developer, a developer-carrying member for carrying and conveying the developer contained in the developer container to a developing zone opposite the image-bearing member, and an elastic blade for regulating the developer carried and conveyed on the developer-carrying member to a prescribed thickness to form a thin developer layer on the developer-carrying member. A developer suitable for use in the above developing apparatus is given by a toner, which comprises a binder resin composition which contains 10 - 70 wt. % of a THF (tetrahydrofuran)-insoluble content and the remainder of a THF-soluble content including a component with a molecular weight of 10000 or below on a GPC (gel permeation chromatography) chromatogram of the THF-soluble content constituting 10 - 50 wt. % of the binder resin.

摘要： An image forming apparatus comprising an electrostatic latent image bearing member and a developing apparatus for developing an electrostatic latent image. The developing apparatus comprises a developer container in which a developer is held, and a developer-carrying member for carrying thereon the developer and transporting the developer to a developing zone. The developer-carrying member has a surface layer of a resin containing at least conductive fine particles and a solid lubricant, and the surface layer has in its relative load curve (Abbot's load curve) a cutting depth Cv of not more than 5 mu m when a relative load length tp is 5 %; and the developer contains a toner and a fine powder pretreated with a silicone oil or silicone varnish.
