Title: Toner composition
Inventor: AOKI TAKAYOSHI
IPC: G03G9/087
Filed: 1987-01-26
Abstract: PURPOSE:To obtain a toner which permits fixing at a lower temp. by using a fluorine-contg. polymer which is specified in mol.wt. and glass transition point of m.p. as a low critical surface energy compd. CONSTITUTION:The fluorine-contg. polymer having <=50,000mol.wt. and >=40 deg.C glass transition point or m.p. is used as the low critical surface energy compd. of a toner compsn. essentially consisting of the compd. which is lower in the critical surface energy than a binder resin and a coloring agent. The mobility of the fluorine-contg. polymer in the toner compsn. acts effectively to accelerate the increase of the concn. in the surface if the mol.wt. of said polymer is confined to <=50,000. A favorable influence is given to the flowability and blocking resistance of the toner if the glass transition temp. or m.p. is specified to >=50 deg.C. The blocking resistance is thereby improved if the fixing temp. of the toner is the same and the low-temp. fixing is permitted if the blocking resistance is the same.

Abstract: PURPOSE:To improve the resolution of a binary image and to automatically identify a binary image from a half-tone image such as a photograph by deciding such a reference picture element that the density difference between itself and an attended picture element is larger than a prescribed value to a white or black edge, then outputting a white or a black pattern to a binarization processing part. CONSTITUTION:In a pre-processing part 13, the presence/absence of an edger detection is decided depending on the density difference:  i( i=Pi-Px) between an attended picture element Px and a reference picture element Pi (i=1-8). If the absolute value of the difference i is smaller than an edge detection threshold TH1 (TH1>0), the absence of edge detection is decided on, and the attended picture element Px is held in an output picture element data Px'; if larger, an edge detection is decided to be present, and a white or a black edge is decided on to be. That is, if a relation  i<=-TH1 is satisfied against the reference picture element Pi, a white edge is decided, but if  i<=TH1 is satisfied, a black edge is decided, and a white or a black data is respectively held in an output picture element data Px'. Thus obtained output picture element data Px' is outputted as a picture element data to the binary processing part 14 in the latter stage.
