An information processing apparatus includes a pasting unit that plays a video and pastes at least one sticky note to the video; a removal unit that removes the sticky note pasted by the pasting unit from the video in a case where a predetermined condition is satisfied; and a display unit that displays the sticky note removed by the removal unit on a time axis so that a date and time at which the sticky note removed by the removal unit is pasted to the video is indicated on the time axis so as to be checked.

A photodetector includes a light emitting portion for applying light, a light receiving portion for sensing the light, and a light guiding memberfor guiding the light from the light emitting portion to a surface to be measured and guiding detection light from the surface to be measured to the light receiving portion. The light guiding member has a sheet-like optical transmission medium, which is disposed at a portion facing to the surface to be measured and transmits the light by internal reflection. The sheet-like optical transmission member has an optical aperture facing to the surface to be measured.

Photodetector, method of using the same, and image forming apparatus

Light is applied by a laser diode onto a photosensitive roll formed with a developed toner image the surface potential of the photosensitive roll to which the light is applied is measured with a surface potential sensor and the toner amount of the developed toner image on the photosensitive roll is derived based on the measured surface potential.

Image formation apparatus, toner amount measurement apparatus, and toner amount measurement method

A toner amount measuring apparatus includes an irradiating unit which divides a flux of laser beams emitted from a laser diode into two fluxes of laser beams by an obtuse-angled prism and makes the two light fluxes interfere with each other to form interference fringes on a photosensitive roll, and a photodetecting unit including an optical sensor for detecting reflection light obtained by reflecting the light constituting the interference fringes from the photosensitive roll.

It is a purpose of the invention to provide a dust protector for an image exposure device capable of preventing particles from sticking to windows or the like of the image exposure device and free from moisture condensation on the windows or the like of the image exposure device as a result of direct exposure of the same to the atmosphere and an image forming apparatus utilizing the same. The purpose is achieved by providing a dust protector for an image exposure device for performing image exposure on a member to be exposed from below with a dust protective member for preventing particles from sticking to at least a member located above an optical path of the image exposure device by covering the image exposure device from above without blocking the optical path of the image exposure device and an air flow generating unit for generating an air flow that prevents particles from entering the region covered by the dust protective member.

A polygon mirror 36 have reflecting surfaces being arrayed such that the reflecting surfaces each having coatings 38 at both ends thereof and the reflecting surfaces having no coating are alternately arrayed. A beam width of a light beam reflected by a coating facet 36A is smaller than a beam width of a light beam by a non-coating facet 36B. Alight beam (first light beam) is deflected by the coating facet 36A, and it lands on a photoreceptor. A light beam (second light beam) is deflected by the non-coating facet 36B, and it lands on the photoreceptor. At this time, a beam diameter of the first light beam on the photoreceptor in the first scan direction is larger than that of the second light beam. When the laser beam is deflected by the non-coating facet 36B, the laser beam is modulated by image data. When it is deflected by the coating facet 36A, the laser beam is modulated by bias data. Both the laser beams are projected to over the entire surface of a projected object within the scanning area, whereby an electrostatic latent image of high contract is formed on the object surface.
