Abstract
An image forming apparatus has a driven image forming part for forming an image. A data supply device has at least one moving portion for supplying data to the image forming apparatus. For example, it may be a hard disk device or a toner sensor having an oscillator, both of which generate noise. A controller actuates the data supply device only during operation of the image forming part, and so the noise is not bothersome to the user.
Claims30
An image forming apparatus having an image forming part for forming an image, comprising:
- driving means for driving said image forming part;
- a data supply device having at least one vibrator for supplying data to said image forming apparatus;
- and
- control means for actuating said data supply device only during operation of said driving means.
An image forming apparatus having an image forming part for forming an image and an image writing device for writing an image to said image forming part, comprising:
- driving means for driving said image writing device;
- a data supply device having at least one vibrator for supplying data to said image forming apparatus;
- and
- control means for actuating said data supply device only during operation of said driving means.
An image forming apparatus comprising:
- an image forming part for forming a image, said image forming part having a photosensitive portion for forming a latent image thereon;
- a developing device for developing said latent image;
- driving means for driving said photosensitive portion;
- a sensor having at least one vibrator wherein an object wherein an object regarding a developing condition is sensed by using vibrations of the vibrator;
- and
- control means for actuating said sensor only during operation of said driving means.
An image forming apparatus having an image forming part for forming an image and an image writing device for writing an image to said image forming part, comprising:
- first driving means for driving said image forming part;
- second driving means for driving said image writing device;
- a data supply device having at least one vibrator for supplying data to said image forming apparatus;
- and
- control means for operating said data supply device only during a time period from when said second driving means begins driving to when said first driving means begins driving.
An image forming apparatus having an image forming part having a photosensitive medium for forming an image and an image writing device for writing a latent image to said photosensitive medium, comprising:
- first driving means for driving said image forming part;
- second driving means for driving said image writing device;
- a sensor having at least one vibrator wherein an object wherein an object regarding a developing condition is sensed by using vibrations of the vibrator;
- and
- control means for actuating said sensor within a time period from when said second driving means begins driving when to said image writing device begins writing.
An image forming apparatus having an image forming part for forming an image and an image writing device for writing a latent image to said image forming part, comprising:
- a photosensitive device comprised in said image forming part and holding the latent image thereon;
- a developing device comprised in said image forming part for adhering the latent image with toner;
- a transferring device comprised in said image forming part for transferring the toner to a recording medium;
- a first driving means for driving said image-forming part;
- a second driving means for driving said image writing device;
- a data supply device having at least one moving portion for supplying data to said image forming apparatus;
- and
- control means for actuating said data supply device within a time period from when said transferring device finishes transferring to when said second driving means fully stops.
