    • To determine whether a record medium loaded on a drive has character information in a management area of the record medium corresponding to data received from the drive and to obtain the character information when the record medium has the character information as the determined result. A system includes an optical disc drive and a host computer 53 connected through an interface 42, wherein the drive has a servo and signal processing portion 30, a system controller 41, and a CD-ROM signal processing portion 50. The servo and signal processing portion 30 reproduces data from a disc 21. The system controller 41 controls the entire operation of the drive. Return data is sent from the drive to the host computer 53 corresponding to a read table of contents (TOC) command received from the host computer 53. A code that represents the data length is contained in a header of the return data. With the code, it is determined whether or not the disc 21 is a CD-TEXT disc. When the, disc is a CD-TEXT disc as the determined result, the read TOC command is re-issued. Thus, CD-TEXT data is obtained.

    • An electrophotographic photoreceptor, in which the increase of VL is controlled below 15 V by controlling the content ratio M (ppm) of a charge transporting material CTM2 to a charge transporting material CTM1 within a specific range, wherein the ionization potential Ip(2) of the CTM2 is smaller than the ionization potential Ip(1) of the CTM1 in the constituent of the photosensitive layer, and thereby the electrophotographic photoreceptor has only a little reduction of image concentration. A method for producing an electrophotographic photoreceptor having ΔVL which is controlled below 15 V, wherein, in a case where the ionization potential of the charge transporting material used in the previous run of production is small, ΔVL can be set below 15 V by using, in the next production, a dip coating liquid, which comprises, as a constitutive material, a charge transporting material in which the difference between the ionization potential of the current material and that of the previous material is set below 0.25 eV.

    • The object of the invention is to provide a highly characteristic and lesser defective image using an electrophotographic photoreceptor which can be produced with a better coating property and which is highly sensitive and hardly loses the electrostatic stability during repeated use. A water-soluble or water/alcohol-soluble polyvinyl acetal and an inorganic pigment are involved in an underlayer provided between a conductive support and a photoconductive layer. Particularly, it is favorable to use titanium oxide as the inorganic pigment, make the ratio of polyvinyl acetal/titanium oxide 1/9-9/1 by weight, make the underlayer 0.5-5 .mu.m in thickness, use the titanium oxide of which the surface is treated with alumina, use the titanium oxide of which the titanium oxide component is 95% by weight or lower and of which the surface is treated with alumina, use the polyvinyl acetal of which the sodium ion concentration is 40 ppm or lower, and use the photo-conductive layer which contains a vinyl chloride-vinyl acetate type copolymer. As for a dispersing medium for coating the underlayer, water/alcohol=1/9-7/3 (ratio by weight) is selected. The aforementioned photoreceptor is applied to an image-forming apparatus using an inversion development process.
