Title:
IMAGE FORMING APPARATUS
Document Type and Number:
Japanese Patent JP2019200402
Kind Code:
A
Abstract:
To provide a technology that can more accurately predict the amount of heat stored in areas corresponding to individual heating areas of an image heating unit to obtain a further power-saving effect.SOLUTION: An image forming apparatus 100 comprises: an image heating unit 200 that has a plurality of heating elements arranged side by side in a longitudinal direction orthogonal to a conveyance direction of a recording material P, and individually heats a plurality of heating areas Ato Awith the respectively plurality of heating elements to heat an image formed on the recording material P; an acquisition unit that acquires information on the image formed on the recording material P and heat history information on the plurality of areas corresponding to the respective heating areas Ato Ain the image heating unit 200; and a control unit that controls heating of the heating areas Ato Aperformed by the image heating unit 200. The control unit corrects control settings used for temperature control of the heating areas Ato A, on the basis of the heat history information on the areas of the image heating unit 200 corresponding to heat history calculation areas CAto CAobtained by dividing each of the heating areas Ato Ainto plurality in the longitudinal direction.SELECTED DRAWING: Figure 8
