摘要： A developing apparatus for an image forming apparatus forms an electrostatic latent image corresponding to an image information signal on an image bearing member. The developing apparatus includes a developer carrying member which bears and conveys a two-component developer containing a non-magnetic toner and a magnetic carrier for forming a toner image by developing the electrostatic latent image formed on the image bearing member. Convexities and concavities are formed on a surface of the developer carrying member. An average peak-to-peak spacing (Sm) of the convexities and concavities is set at ⅓ to 6 times of a weight-average particle diameter of the magnetic carrier (D) (D/3≦Sm≦6*D). An average roughness at ten points (Rz) on the surface of the developer carrying member is set at {fraction (1/10)} to ½ times of the weight-average particle diameter of the magnetic carrier. A number of concavities which are 1 &mgr;m to 10 &mgr;m wide and 0.2 &mgr;m or more deep is smaller than 10 within a spacing of 100 &mgr;m in a surface profile of the developer carrying member. The surface of the developer carrying member is prepared by blasting the surface with definite spherical particles having a weight-average diameter d and a weight-average particle diameter D of the magnetic carrier, according to the following relation: D≦d≦10D.

摘要： A method of and an apparatus for recording an image on a recording medium. A heat-sensitive sheet having a light-transmissive base sheet provided with a heat-fusible supercooled substance layer is made to abut a copy original such that the heat-fusible supercooled substance layer faces the original image to be copied while flashlight is projected onto the base sheet of the heat-sensitive sheet. Thus, the image portion of the copy original to be copied absorbs the light transmitted through the heat-sensitive sheet and thereby generates heat so that an adhesive area containing a pattern corresponding to the original image is formed on the supercooled substance layer. After the heat-sensitive sheet has been removed from the copy original, such an adhesive area is transferred to the recording medium owing to the adhesiveness of the adhesive area.
