Abstract: The image forming apparatus includes a first placement member, a second placement member, a third placement member and a fourth placement member which contact with a placement surface for placing the image forming apparatus thereon, and which support the image forming apparatus, a side plate of the image forming apparatus, and supporting means as the supporting member for supporting the third placement member and the fourth placement member movably in a vertical direction of the image forming apparatus. This can prevent the deformation of the image forming apparatus without increasing the load on a bottom plate.

Abstract: A graphics processing apparatus for computing the distance between two three-dimensional graphic elements without reducing the user's operating efficiency is provided. The graphics processing apparatus selects, from among three-dimensional objects displayed on a display, graphic elements between which the distance is to be computed, determines a projection reference in accordance with a viewing direction and geometric information on the graphic elements, and determines a projection plane in accordance with the projection reference. The graphic elements are projected onto the determined projection plane, and the minimum distance between the selected graphic elements is computed from the projected graphic elements.

Abstract: A toner supply apparatus includes a first toner container; a first feeding member for feeding toner in the first toner container; a second toner container for receiving the toner from the first toner container; a second feeding member for feeding toner in the second toner container; a third toner container, detachably mountable relative to a main assembly of the toner supply apparatus, for receiving in the toner from the second toner container; wherein when the toner is supplied into the third toner container, the first feeding member is driven in accordance with a toner supply amount, and the second feeding member is substantially continuously driven irrespective of the toner supply amount.

Abstract: An image heating apparatus includes a heater; a film sliding on the heater, a roller forming a nip with the heater with the film being put between the roller and the heater, the nip nipping and conveying a recording material bearing an image thereon with the image on the recording material being heated by heat from the heater through the film, an elastic member for pressing the heater to a side of the roller, a pressing member for pressing an end portion of the elastic member on a side thereof opposed to a side of the heater, and a supporting portion for supporting the pressing member, the supporting portion including an opening portion through which the elastic member can pass.

Abstract: A developing apparatus for developing an electrostatic image formed on an image bearing member, having a developing container containing a developer including toner and carrier, a partition portion for partitioning the developing container into a first chamber for developing the electrostatic image on the image bearing member and a second chamber for receiving the supply of the toner, a circulating device for circulating the developer between the first chamber and the second chamber, wherein the second chamber is provided so that a side thereof for receiving the developer from the first chamber may be located below the first chamber, and may be upwardly inclined toward a side for delivering the developer to the first chamber, and a toner supplying path for supplying the toner to an area of the second chamber which is located below the first chamber, wherein the toner supplying path is provided so that at least a portion thereof may be opposed to the first chamber with the partition portion interposed therebet

Abstract: An image heating apparatus in an image forming apparatus includes a temperature detecting element, an elastic member for pressuring the temperature detecting element and a film for covering the temperature detecting element. Conventionally, since the elastic member whose width is smaller than the width of the film completely covers the temperature detecting element and the elastic member, it has been necessary to prevent the film from interfering with and riding onto a heater holder equipped beside those parts. For improvement of the above problem, the elastic member whose width is larger than the width of the film is provided to be able to pressure an edge of the film.

Abstract: The image heating apparatus has a heater, a film sliding against the heater, a roller forming a nip together with the heater via the film, a holding member for holding the heater, and a supporting member for supporting the roller. In the image heating apparatus, a recording material bearing an image is nipped and conveyed in the nip and the image on the recording material is heated by heat from the heater via the film, and the holding member is directly supported by the supporting member.

Abstract: An image heating apparatus including a heater, a temperature detecting element for detecting a temperature of the heater, a supporting member for supporting the temperature detecting element, and a biasing member for biasing the supporting member toward the heater. The biasing member biases a surface of the supporting member opposite to the surface in which the temperature detecting element is provided.
