IMAGE FORMING METHOD

PROBLEM TO BE SOLVED: To provide an image forming method which enables the formation of a picture having high picture concentration and high picture quality in the formation of the picture by developing an electrostatic latent image formed in a photosensitive layer of a photoreceptor by means by a one-component toner. SOLUTION: In the image forming method, the toner contains any multiple oxide selected from a group consisting of the following multiple oxides (1)-(5), the absolute value of charged amount of the toner is set 1-40 and the absolute value of the product of the charged amount and the thickness of a layer of the toner carried on a development roller is set 0.01-1: (1) a multiple oxide containing any manganese element of tetravalent, trivalent or tetravalent/ bivalent and trivalent iron element, (2) a multiple oxide containing trivalent manganese element and trivalent iron element, (3) a multiple oxide containing trivalent copper element and trivalent iron element, (4) a multiple oxide containing trivalent copper element and trivalent chromium element and (5) a multiple oxide containing bivalent copper element, trivalent iron element and trivalent chromium element.
